For example, if you choose to participate in write-on, you will be partially judged on the accuracy of your Bluebooking. Similarly, Bluebooking can provide anybody reviewing a writing sample an easy way to make a âfirst cutâ and divide applications between those that will get a closer look and those that will not.
A spectrum analyzer is a device used to examine the spectral composition of some electrical, acoustic, or optical waveform. Often, it measures the power spectrum.
A distortion analyzer is an electronic test instrument that measures the accuracy of an electronic circuit at reproducing a wave.For instance, an audio amplifier might have a sine wave input to it, and the distortion analyzer measures how close the output is to a sine wave.If the output is clipped, the wave will be distorted, and the analyzer will measure the amount of harmonics present.mplifiers will frequently have a Total Harmonic Distortion plus Noise specification which is an accurate term for the quantity measured by a distortion analyzer. There are many manufacturers of distortion analyzers. The Hewlett-Packard models 331a and 333 are laboratory standard instruments.
