Abstract of the Disclosure, An electrical signal multiplier comprises a pair of signal transmission gates each including a pair of parallel coupled, opposite conductivity field effect transistors. An input signal which, for example is to be, demodulated, is applied in balanced push-pull relation to, each of the transmission gates respectively. Balanced, push-pull reference switching signals render the transmission gates conductive and non-conductive in comple-, mentary fashion, during alternate switching intervals. Output (demodulated) signals are provided alternately at signal outputs of the transmission gates. - 1 -
