PCT No. PCT/SU80/00121 Sec. 371 Date Aug. 4, 1981 Sec. 102(e) Date Aug. 4, 1981 PCT Filed Jul. 31, 1981 PCT Pub. No. WO81/01762 PCT Pub. Date Jun. 25, 1981.A quadrature stepwave frequency converter comprises two variable-gain circuits, each connected to a sign reversing circuit adapted to reverse the sign of the gain. The absolute value of a converter gain depends on the number of the control inputs of the variable-gain circuits, at which binary signals have changed in a certain direction. The converter further comprises a sequencer 9 having two outputs respectively connected to the control inputs of the sign reversing circuits and its remaining outputs connected to the control inputs of the variable-gain circuits, so that the instants of changes in the binary signals at the mutually corresponding control inputs of different variable-gain circuits coincide.
