The paper presents a method for the design of partial response data transmission filters. Two classes of filters are considered: class 1 and class 2. An analytical theory is developed for the design of timing-jitter-suppressed, low intersymbol interference class 1 filters. This is then extended to the generation of class 2 filters. The optimal poles and zeros of the filters are located by means of an iterative numerical search. Numerical results show that the filters have optimal performance in both time and frequency domains. Filter responses to a rectangular input pulse (NRZ) are given and the performance characteristics are discussed.
