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 ...
This brief paper examines the most important differences between the responses of the Fast Fourier Transform (FFT) and Polyphase Discrete Fourier Transform (DFT) filter banks. In general, while the ...
The path to real-time wideband channelization is camouflaged by different techniques. Among the competing approaches are Pipelined FFT, polyphase DFTs, multiple digital downconverters (DDCs), and both ...
