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 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 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 ...
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 ...
The QF1D512 SavFIRe configurable finite impulse response (FIR) filter chip can follow any analog-to-digital converter (ADC) in industrial monitoring applications like vibration sensing, flow ...
Georgia Tech has developed a general-purpose MMIC (monolithic microwave IC) for the direct filtering and processing of microwave and millimeter-wave signals. The aim is to reduce radio power ...
The LMS adaptive filter is the main functional block in high channel-density line echo cancellers for VOIP. In this paper, we describe an LMS adaptive FIR filter IP and estimate its performance when ...
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 ...
