Bacteria, algae and other organisms thrive under warm water conditions this is obviously harmful not just for athletes but the general public in a commercial swimming pool, for competitive pools the water should be no higher than 82Â°F (28Â°C), for recreational pools the recommended maximum is 84Â°F (29Â°C).
Distortion is also used as a musical effect, particularly with electric guitars. The addition of noise or other outside signals (hum, interference) is not deemed distortion, though the effects of quantization distortion are sometimes deemed noise. A quality measure that explicitly reflects both the noise and the distortion is the Signal-to-noise-and-distortion (SINAD) ratio.
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.
