Abstract
A trigger signal detection apparatus includes: a clock gating circuit which is supplied with a trigger signal and a clock signal and outputs the clock signal; a trigger signal processing circuit which outputs a first signal only for a predetermined time when the clock signal is supplied from the clock gating circuit; a counter which operates in response to the trigger signal, thus outputting a count value of the clock signal; and a time set-up circuit which outputs a second signal to the trigger signal processing circuit when count value supplied from the counter reaches a preset value, and the trigger signal processing circuit stops outputting the first signal when the trigger signal processing circuit receives the second signal.
