Sažetak
The composed audio test signal (CATS) is formed by mixing three mutually independent composed sawtooth signals (CSSs), which are a special type of pseudorandom signal. The CATS closely follows the characteristics of natural signals, and its behavior is controlled by the well-defined and configurable parameters. The amplitude probability density function of the CATS follows Gaussian distribution. Furthermore, second and third CSS sequences are generated using the perturbed parameters of the first one. CATS methods employ efficient cross correlation between input and output to recover the periodic impulse response (PIR) of the system being measured. The frequency response can then be found by taking the discrete Fourier transform of the impulse response.
