Decimation (signal processing) Decimation (signal processing) In digital signal processing, decimation is the process of reducing the sampling rate of a signal. Complementary to interpolation, which increases sampling rate, it is a specific case of sample rate conversion in a multi-rate digital signal processing system.

Carbon filtering It is also used in cigarette filters. Active charcoal carbon filters are most effective at removing chlorine, sediment, volatile organic compounds (VOCs), taste and odor from water. They are not effective at removing minerals, salts, and dissolved inorganic compounds.

Understanding the Post-Injection Problem By Ron Kotrba | April 15, 2008. Fuel dilution in diesel engines is not a new issue, but it's one that's gained greater attention recently as lower emissions thresholds went into effect last year. Meeting the 2007 regulations requires the incorporation of diesel particulate filters to trap soot.

Deblurring Images Using the Blind Deconvolution Algorithm Open This Example. This example shows how to use blind deconvolution to deblur images. The blind deconvolution algorithm can be used effectively when no information about the distortion (blurring and noise) is known. The algorithm restores the image and the point-spread function (PSF) simultaneously.tep 2: Simulate a Blur. Simulate a real-life image that could be blurred (e.g., due to camera motion or lack of focus). The example simulates the blur by convolving a Gaussian filter with the true image (using imfilter).

Fuel Filter Fuel filters are small components that are designed to keep contaminants out of your fuel. If dust, rust, or chipped paint enters your fuel, then it can cause rapid wear and tear for your fuel pump and injectors. This is where the fuel filter comes in. This simple filter prevents such harmful particles from entering your fuel, keeping your engine working like a charm and boosting your vehicle’s performance.

- fuel filters attached, but these are only the final line of defense against fuel contami-nation—a backup for the primary filter or filters. Depending on engine make and model, the final filter, mounted on the engine just before the injection pump, will have a single-pass retention (pore size) rating of 2 to 10 microns (a micron is a thousandth of a millimeter). This is the size that most en-gine manufacturers figure will protect in-jector pumps and nozzle tips from damage. Two microns is pretty small stuff; and be-

Diesel particulate filter Partial filters. There are a variety of devices that produce over 50% particulate matter filtration, but less than 85%. Partial filters come in a variety of materials. The only commonality between them is that they produce more back pressure than a catalytic converter, and less than a diesel particulate filter.

Introduction to DSP - filtering: frequency selective process Introduction to DSP - filtering: frequency selective process. Filtering is a process of selecting, or suppressing, certain frequency components of a signal. A coffee filter allows small particles to pass while trapping the larger grains. A digital filter does a similar thing, but with more subtlety.

- Bilateral filter is a nonlinear filter that is a mixture of range filter and domain filter, the previous one preserves crisp edges and the latter one filters noise. The intensity value at each pixel in an image is replaced by a weighted average of intensity values from nearby pixels.

Antialiasing and Anisotropic Filtering Anisotropic filtering improves the clarity and crispness of textured objects in games. Textures are images containing various types of data such as color, transparency, reflectivity, and bumps (normals) that are mapped to an object and processed by the GPU in order to give it a realistic appearance on your screen.s previously mentioned, bilinear and trilinear filtering suffer from resultant quality loss when the sampled textures are oblique with the camera due to both methods obtaining texel samples from mipmaps assuming that the mapped texel is perfectly square in the rendered space, which is rarely true.

- When short delays are mixed with the direct sound, a frequency response called a comb filter is obtained, as shown in figure 3. This is the frequency response of phase-cancellation. This response curve gets its name from the fact that it looks similar to a pocket comb.he comb filter actually consists of both cancellation (at 1kHz, 3 kHz, 5 kHz in the example) and reinforcement (at 2 kHz, 4 kHz, 6 kHz in the example). When you apply feedback to a delay line causing a comb filter the reinforcement and cancellation is made more extreme as shown in figure 10.

- The two most common are the variable ND filters and the extreme ND filters such as the Lee Big Stopper. Variable neutral-density filter The main disadvantage of neutral-density filters is that to be entirely flexible in your shooting you need to carry a range of different NDs.

- Filters that are ISO 12312-2 certified not only reduce visible sunlight to safe and comfortable levels but also block solar UV and IR radiation. To date four manufacturers have certified that their eclipse glasses and handheld solar viewers meet the ISO 12312-2 international standard for such products: 1  Rainbow Symphony. 2  American Paper Optics. 3  Thousand Oaks Optical.  TSE 17.

How to Choose Ductless Range Hoods How to Choose Ductless Range Hoods. A ductless range hood, also called a recirculating range hood, is one that does not exhaust air outdoors through a duct. Instead, this type of hood draws air through a filter before circulating it back into the room. The filter is intended to remove as much of the smoke, steam, oil, and odor as possible from the air. Ductless range hoods are suited for remodeling projects where ductwork is not already installed.

- It is the intent of this article to explain compressors and the process of compression so that you can use this powerful process in a more creative and deliberate way. Compressors and limiters are specialized amplifiers used to reduce dynamic range--the span between the softest and loudest sounds.

Anisotropic Filtering (AF) Anisotropic Filtering (AF) Anisotropic filtering is a filtering technique used in 3D computer graphics in which the number of texture samples generated changes depending on the angle that the surface to be rendered is in relative to the camera.

Respirator A half face particulate (air-purifying) mask is generally worn to protect the wearer from dust and paint fumes. A respirator is a device designed to protect the wearer from inhaling harmful dusts, fumes, vapors, or gases. Respirators come in a wide range of types and sizes used by the military, private industry, and the public. Respirators range from relatively inexpensive single-use, disposable masks to more robust reusable models with replaceable cartridges.

The difference in the time arrival to your ears of the direct sound versus the sound reflected off of the ground causes various frequencies to be cancelled or reinforced.omb filtering is one of the main ingredients in the distinctive sound of a jet aircraft passing overhead.

Decimation (signal processing) Decimation by an integer factor, M, can be explained as a 2-step process, with an equivalent implementation that is more efficient: 1  Reduce high-frequency signal components with a digital lowpass filter.  Downsample the filtered signal by M; that is, keep only every Mth sample.

- Too many variables exist regarding inlet air filters. We call this process puffing the filters, because of the sound the process emits. If the filters becomes wet and then are exposed to contamination, it is obvious this contamination will stick like it was glued. The air pulses will then find the path of least resistance and tear the weak paper filters. On the other hand, certain contaminates can be removed while puffing offline dry and cannot be removed while puffing online dry or wet.

The Compressor is one of the most misunderstood effects of all â hereâs what it does, and why you might need one Put simply, a compressor reduces dynamic range. The dynamic range is the range from the quietest point to the loudest point in a given piece of audio. So, if that was, say, a guitar performance, that would most likely be from silence up to the loudest bit of the performance.

- Most home owners spend between $968 and $1,466 to have a sump pump installed. The actual cost that a home owner can expect to pay for installation will depend on the type of pump, whether there is already a hole for drainage, and whether additional features and accessories are needed.
