Abstract
A pulse generating electronic circuit is utilized as a matching network between a line operated video tape recorder (VTR) and a battery powered portable camera. Through the use of appropriate logic circuitry, the pause control button of the VTR, which normally operates to provide an on or off signal pulse, is disabled, and the time delay experienced by a camera activated electrical signal passing through the VTR electronics is utilized to generate the on or off signal pulse.
