Abstract
A signal meter driving signal is derived from first and second active elements connected in parallel and controlled by opposite phase differential outputs from an IF amplifier. The active elements are biased with a bias voltage which differs by a predetermined amount from the d.c. output of the differential amplifier when no IF input signal is present.
