Abstract :
Existing forms of conventional electronic cross correlator cannot meet the increased bandwidth requirements for wide-band system testing. It is shown here that a technique based on the facilities of a sampling oscilloscope can provide very wide-band operation and yet requires only low-speed logic and a low-frequency multiplier. The method also lends itself to computer operation.
