ABSTRACT:
A synchronization signal generator includes a delayed signal generator receiving an original oscillation signal from a ceaselessly operated oscillator to generate a plurality of delayed signals having different delay times from the original oscillation signal, and a trigger signal generator receiving a synchronization signal for generating a trigger signal. There is provided a selector circuit receiving the delayed signals and the trigger signal for selecting, among the delayed signals, only the delayed signal in synchronism with the trigger signal with a substantially constant delay.
