A timing generator having no dead time and capable of altering a timing at any time. A rough timing pulse generating means suitably specifies one of a plurality of input clock pulses to generate a rough timing pulse for a desired timing. A timing vernier delays the rough timing pulse for a suitable delay time to generate a minute timing pulse. In a compensating circuit, the minute timing pulse is input to a delay circuit having one input terminal and plural output terminals, and one of the outputs at the output terminals for delay is selected by a multiplexer. When the multiplexer selects an output whose delay time is not zero, a next pulse can be input from the timing vernier to the dead time compensating circuit so that no dead time occurs.
