Abstract
A pair of square waves of a carrier frequency are applied respectively to a pair of amplifier circuits having a common output circuit. The output circuit is connected so that the energy therein is dependent upon the relative phases of the square waves. A further circuit is provided for varying the relative phases of the two square waves, so that the output from the output circuit is in the form of amplitude modulated oscillations.
