Abstract:
Methods and systems for blending the audio output from a received FM signal between stereo and mono in which the L−R (left-minus-right) gain of the FM MPX may be adjusted as a function of RF signal to noise ratio (SNR) and the L+R (left-plus-right) noise level. During blending, the L−R gain based on the RF SNR and L+R noise may be reduced in a manner such that the total noise is kept substantially constant throughout the stereo-to-mono blend region.
