Method For Distortion Measurements Using pseudo-Random Signal

Distortion measurements should give us objective evaluation and comparison of different electroacoustical devices. Modern methods for distortion measurements give us partial information about certain devices, because used test signals don't have characteristics of natural signals &#8211 ; ; speech and music. Proposed combined audio test signal (CATS) consists of three sawtooth signals, and has characteristics of natural signals. Frequency components of the CATS spectrum are unevenly distributed, so intermodulation components fall between components of the original spectrum at the input of the measured system. Using peak search method intermodulation components can be extracted form original signal, and their comparison can be made.
