Application of the Fast Fourier Transform to Digital Audio Electrical and Acoustical Measurement Techniques
This paper discusses applications of single and dual channel FFT analyzers to evaluate digital audio devices, such as Compact Disc players and PCM audio processors. With an appropriate choice of excitation and FFT instrument a very detailed analysis of the analog output signal is possible and surprisingly easy to perform. The informatin obtained in most cases allows the user to diagnose the function of both digital and analog circuitry involved with the least possible interaction with internal hardware.
