Circular buffer for fir filter
WebCircular buffers are useful in DSP programming because most implementations include a loop of some sort. In the filter example, all the coefficients are processed, and then the … WebWhat Is a FIR Filter? The use of FIR filters (or finite impulse response filters) has grown in popularity in the live sound world as digital signal processing (DSP) for loudspeakers becomes more and more sophisticated.
