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 ...

Finite impulse response (FIR) filters are at the heart of modern control systems, prized for their inherent stability and exact linear phase response. Recent advances have focused on optimising filter ...

Why use FIR filters, anyway? With the availability of easy-to-use IIR filters in Cypress Semiconductor’s PSoC Creator’s Filter tool, I’ve spent a lot of time over the years telling people the ways in ...

Digital filters are always an interesting topic, and they are especially attractive with FPGAs. [Pabolo] has been working with them in a series of blog posts. The latest covers an 8th order FIR filter ...

All too often, designers spend so much time focusing on the specification and selection of their complex, higher cost devices, such as processors, FPGAs, and ADCs, that they don’t fully take into ...
