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 ...

The modern, advanced CMOS direct radio frequency (RF)-sampling data converter has been eagerly awaited by system design engineers for several major end-equipment manufacturers. This includes ...

The first part of this series described how data flows through processing steps that create a moving average of stock prices over 65 days. Finite-impulse-response (FIR) filters use the same data-flow ...

Building upon the Pipelined Frequency Transform (PFT) architecture, we have developed a new filter-bank technique that allows asymmetrical-band splitting of a given spectrum of frequencies. A few ...
