FIR Filter, Effect of Quantizing the Impulse Response.

Cuthbert Nyack
In this applet the effect of quantization of the Impulse Response on the Frequency Response of the filter is illustrated.

The number of bits used for the quantization is Nb and changing Nb shows that at least 16 bit quantization is required to reproduce the minimum attenuation in the Frequency Response.
