Variable fractional delay (VFD) filter design has become increasingly significant in digital signal processing, offering the flexibility to delay signals by non-integer amounts. This technology is ...

Across a range of applications, the two most common functions implemented in FPGA-based high-performance signal processing are finite impulse response (FIR) filters and fast Fourier transforms (FFTs).

Digital signal processing is ubiquitous in modern electronic systems, from MP3 players to digital cameras to wireless handsets. One of the mainstays of a DSP designer’s tool box is the FIR ...

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 ...

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 ...
