Abstract: A signal modulation system in which clock signals can be modulated with first and second modulation signals which are applied to the clock signals through first and second switching circuits. A control means involving threshold devices is so responsive to the operation of the switching circuits that at any one time only one of the switching circuits is able to pass modulation signals to the clock signals.
