The implementation is based on …
WebApr 18, 2024 · A polyphase filter bank is a multi-rate filter structure combined with a DFT to extracts sub-bands from an input signal. It is simply a computational structure for applying resampling and filtering to a signal. In image or signal processing, an instrument needs to do Discrete Fourier Transform (DFT) on input signals.
