WebThis chapter describes some signal processing applications that use the DFT to perform specific time domain filtering tasks. Two basic filtering tasks can be performed with DFT: (1) convolution or correlation between two arbitrary arrays and (2) narrowband channelization. The DFT gives access to the computational efficiency of the FFT. WebDec 1, 2002 · Finite Impulse Response. A finite impulse response (FIR) filter is a filter structure that can be used to implement almost any sort of frequency response digitally. An FIR filter is usually implemented by using a series of delays, multipliers, and adders to create the filter's output. Figure 2 shows the basic block diagram for an FIR filter of ...
