Maximally flat low-pass digital differentiators

Research output: Contribution to journalArticlepeer-review


This paper describes the design of type HI and type IV linear-phase finite-impulse response (FIR) low-pass digital differentiators according to the maximally flat criterion. We introduce a two-term recursive formula that enables the simple stable computation of the impulse response coefficients. The same recursive formula is valid for both Type III and Type IV solutions.
