Abstract
A high-speed, solid-state, electronic circuit for alternately coupling two separate video signal paths to a third video signal path in response to high frequency square wave excitation, the circuit utilizing two dual-gate metal oxide semiconductor field effect transistors having oppositely phased signals applied to respective switching gates for cancellation of switching transient signals.
