Poliharmonichni methods of measurement frequency response audio channels and paths
The article analyzes the methods of measuring theamplitude-frequency responses of the transmit audio information identified advantages and disadvantages of known methods of measurement. A new method of measurement, which allows a quick response in addition to channel information and other important parameters, such as group delay, distortion factor and others. Showed APZT device, built on the proposed method of measuring parameters of audio paths, and given the options. AFC is a graph obtainedusing the proposed method.
