A demonstration of FIR filters in operation completes this series of columns. For this demonstration, I used an ARM mbed module with an NXP LPC1768 microcontroller (ARM Cortex-M3 processor). Although ...

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 ...

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 ...

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 ...

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 ...

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 ...
