DEFINITION

Classification: 455/332

Push-pull:

(under subclass 323) Systems wherein the frequency conversion means includes two paths for either the modulated input carrier wave or locally generated signal wave, or both, which have a common output, the two paths being connected electrically in parallel with respect to the input and output of the paths the voltages in the two paths being 180 of phase with respect to each other.
