Digital signal processors (DSPs) continue to receive a great deal of attention in new product design. For example, digital filter design reflects the importance of understanding and using this ...

Variable fractional delay (VFD) filter design has become increasingly significant in digital signal processing, offering the flexibility to delay signals by non-integer amounts. This technology is ...

As a parting shot, I pointed out that there are three quadratic terms there with unity coefficients of z 0 – and there are three deep nulls in the filter’s gain response, as was shown in the figures ...

With the constant downward price pressure on consumer electronics devices, one area that typically gets compromised is audio quality. This compromise is often reflected by the manufacturers' choice of ...
