Linear-Phase Versus Minimum-Phase CCD Transversal Filters
It is shown that the effect of charge-transfer inefficiency on the frequency response of CCD transversal filters is a sensitive function of the actual zero locations and in contrast to the observation made in the paper by Foxall et al. (1977), the minimum phase design is not always less sensitive than its linear-phase prototype.
