Web1.2 FIR filter An FIR filter is essentially a convolution of the signal with the filter coefficients. The number of coefficients determines the minimum notch size with respect to the signal bandwidth. Having a large number of coefficients allows precise notching of narrow-band noise signals, thus minimising the amount of information lost.
