Abstract

An arrangement for mixing two electrical input signals without producing an image frequency, characterized in that the two input signals are applied to a selective comparator device that responds at times when the instantaneous values of the two input signals are identical, but from those moments it selects those in which the product of the derivatives of the two input signals always have the same sign at one time, and delivers an output signal only at those selected instants.
