Over the years controversy has raged back and forth on whether brick wall filters used in digital audio (namely for CD playback systems) exhibit phase shifts in the audio band (20Hz to 20kHz). Audio ...
Active audio filters may be used to compensate problems in frequency response of audio systems and loudspeakers. This paper deals with analog filters. These filters can produce a response that is ...
Digital signal processing frequently uses finite precision in representing signal and coefficient data, and finite precision arithmetic in performing computations. But the system performance – the ...
