Previous columns have described how analog and switched-capacitors filters work and provided a real example of each. Now on to digital filters that process discrete-time digital values, rather than ...

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 ...

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 ...

FIR filters used for signal manipulation in the digital domain have either a symmetric or anti-symmetric impulse response, i.e., where N is the order of filter. This Design Idea extends the same ...

Finite Impulse Response (FIR) filters are ubiquitous in digital signal processing, valued for their inherent stability and exact linear-phase response. The design challenge centres on selecting a ...

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 ...
