The figure illustrates a simple pulse -position modulation circuit and its waveform. The position of output voltage UA is controlled by the modulation input signal UE. 555 constitute a non - steady-state free oscillation circuit, and the gate voltage and time delay is changed by the UE control, therefore the position of the output pulses is controlled by the modulation signal.
