Analysis of a Commutated Network

A theoretical analysis of the comb-filter properties of synchronously commutated capacitors is presented. The introduction of extraneous frequencies due to the time variance of such a network is investigated. The effects of the number of commutator segments and the input and output time constants on the bandwidth and phase shift are considered. The use of this integrator circuit as a postdetection filter of a spinning-goniometer radio direction finder is discussed.
