摘要：

The factors which have an influence on the stability of the operation of carrier telegraph (CT) channels are analyzed. One of the ways of designing filters which have the required stability of the frequency characteristics and do not contain inductances is based on using active RC-circuits and analog gated circuits. As a result of an analysis of filters of this kind, a parametric filter circuit was proposed using gated capacitors and conversion of the signal spectrum. A filter of this kind is called a ″gated filter-converter″ (GFC). A block diagram of the CT equipment using GFC is presented together with its principal characteristics.
