Abstract
A frequency modulation (FM) radio receiver includes a processing unit that may generate a magnitude value corresponding to a signal strength of each of a plurality of digital samples of a received FM signal. The receiver also includes a noise estimation unit that may filter the magnitude values using a high pass filter and may generate a noise value representative of a noise portion of the received FM signal based upon the filtered magnitude values.
