PURPOSE:To make small the size of transmission circuit, by giving the signal modulating clock pulse with the input signal, to two sets of full-wave rectifying circuits via pulse transformers. CONSTITUTION:With the input terminal 2 fed with the signal S in H level, when the clock pulse CP is fed with the pulse CP at H level, a current flows to the winding of a pulse transformer T1 toward the arrow A and with the pulse CP at L level, the current toward the arrow B flows. No current flows to the pulse transformer T2 in any case. Next, when the signal of L level is fed to the terminal 2, a current flows only to the winding of the transformer T2 alternately. Thus, since the phase control of the clock pulse is made at the primary side of the pulse transformers, no transformer for phase control is required, allowing to constitute the transmission circuit only with two pulse transformers. |
