Abstract
In a digital difference-frequency mixer equipped with a bistable trigger stage, the following gates are proposed: a first EXOR-gate to which a first signal and a second signal are directly applied, a second EXOR-gate to which these two signals are applied each delayed by one quarter period, a first AND-gate to which the output signals of the first EXOR-gate and the second EXOR-gate are directly applied, a second AND-gate to which these output signals are applied in inverted form and an RS-flip-flop. The output signal of the first AND-gate is applied to the set pulse input of the RS-flip-flop and the output signal of the second AND-gate is applied to the reset pulse input of the RS-flip-flop.
