Title:
TRIGGER SIGNAL GENERATION SYSTEM AND FRAME SIGNAL WAVEFORM OBSERVATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2005/005997
Kind Code:
A1
Abstract:
A trigger signal generation device includes: a frame synchronization circuit for receiving a frame signal of a predetermined bit rate and outputting a synchronization signal synchronized with the input timing of the head data of the frame signal; a position information output circuit for receiving a synchronization signal outputted from the frame synchronization circuit and outputting position information indicating the input bit position of the frame signal; and a trigger generation circuit for outputting a trigger signal at the timing matched with the bit position where the position information outputted by the position information output circuit is specified by the position specification section. A trigger can be performed accurately at an arbitrary bit position of the frame signal.
