Before we proceed, let's quickly review our filter bank example. Our example, shown in Figure 1, is a size 16 DFT filter bank. The color scheme shows the sample rate change where a 16 MHz input sample ...

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 ...
