Implementation of comb filters by sampled analog techniques.
Bruce Richard Freund · Calhoun: The Naval Postgraduate School Institutional Archive (Naval Postgraduate School) · 1975
The design of sampled analog filters using Z-transform techniques developed in digital filter theory is studied. Both recursive and non-recursive algorithms are implemented and analyzed. Some deviations from theoretical frequency responses are noted. An analog Fourier transformer is constructed by cascading a recursive comb filter and a non-recursive bandpass filter.
