ABSTRACT:
An apparatus for controlling the output of a switching amplifier includes a signal dividing circuit which generates a delayed replica of the carrier signal and a doubled signal having twice the carrier frequency. The doubled signal is effective for establishing a second time delayed signal relative to the first time delayed signal. The first and second time delayed signals are logically operated on so that a three state output representing the carrier signal is attained. A summing amplifier utilizes the two time delayed signals to generate this three state output whereby if the two time delayed signals are out-of-phase, a zero voltage is connected to the drive portion of the switching amplifier thereby limiting the output of the switching amplifier.
