DEFINITION

Classification: 455/210

With carrier amplitude modulation elimination (e.g., specified limiter):

(under subclass 205) Subject matter in which the receiver system includes means for the elimination of amplitude modulation components of the input carrier wave signal.

(1) Note. The amplitude modulation component of the input signal wave may arise from any source external to the receiver but most generally arises at the output of the transmitter.
