Abstract
Methods and systems are disclosed that mitigate stereo noise in FM broadcast receivers by assessing L−R (left-minus-right) and L+R (left-plus-right) levels within tuned FM channels. These assessments are used to facilitate control of a blend from stereo output signals to mono output signals in order to reduce and mitigate stereo noise and distortion in the audio outputs. The side effects of the disclosed systems and methods are unobtrusive as compared to prior blend-to-mono techniques.
