Transitional Halpern-Thomson filters
S M Lazovic, M. Radmanovic · Electronics Letters · 1975
A new class of lowpass filter, with all transmission zeros at infinity, having a monotonic passband response is described. The transfer function of these filters, referred to as transitional Halpern-Thomson (t.h.t.) filters, depends on a variable parameter that enables a tradeoff between, the overshoot and the risetime in response to a unit-step input.
