How does signal delay and triggering unit help in EMG? Correct Answer The delayed signal is actually signal acquired from individual muscles

The signal delay and trigger unit of EMG is used to examine signal from individual muscle fibers. For this purpose, there is a special electrode of 25 micron diameter which has 14 needles like pick up surfaces. In order to receive and analyze signals properly, a delaying sweep is used. This allows for the signal to be taken from every needle individually, one at a time. This allows for better processing of the signal as well.
