A time division communication system tends to develop noise responsive to variations of the output of the voltage supply which occur as the time slot signals switch on or off to thereby vary the load demand placed upon the power supply. The invention eliminates these voltage variations by providing a second and complementarily acting switch which applies a load across the power supply when the load of the time slot signals is removed. This way, the total load across the power supply remains generally unvarying.
