ABSTRACT:
A noise suppressor, and associated method, suppresses periodic noise components of a communication signal. The period of the periodic noise components of the communication signal is determined by correlating the communication signal with the communication signal, delayed by various delay amounts. Once the period of the noise component portion is determined, a periodic signal exhibiting a corresponding periodicity is generated and subtracted from the communication signal. The resultant, difference signal forms a noise-suppressed communication signal. When embodied in a radiotelephonic device, background noise formed of an engine sound caused by the running engine of a motor vehicle at which the radiotelephonic device is operated can be suppressed during operation of the noise suppressor.
