ABSTRACT:
A logic analyzer uses a single tapped delay line and a single array of sampling cells for high speed digital signal acquisition, by controlling both edges of a substantially 50% duty cycle clock signal to drive a delay line buffer chain. The chain operates continuously; there being no need for interruptions for precharge intervals. Thus, the need for a second delay line buffer chain is eliminated.
