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 ...

The role of filters in sampling-rate conversion process has been discussed in Chapters II and III. Filters are used to suppress aliasing in decimators and to remove images in interpolators. The ...

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 ...

Serial data out of networking SERDES have reached rates as high as 28Gbps and are continuously evolving. At such high data rates, even small PCB traces act as transmission lines, degrading the signal ...

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 ...
