Abstract:
An ideal differentiator has a frequency response that is linearly proportional to frequency. Full Wideband differentiator has an anti-symmetric unit sample response. FIR approximations are preferred to IIR because of the stability and linear phase response offered. In this paper we consider the design of an FIR differentiator based on frequency sampling technique.
