A wireless receiver (10) includes a down converter module (210) operable to deliver a signal having a signal bandwidth that changes over time, a dynamically controllable filter module (200) having a filter bandwidth and fed by said down converter module (210), and a measurement module (295) operable to at least approximately measure the signal bandwidth, said dynamically controllable filter module (200) responsive to said measurement module (295) to dynamically adjust the filter bandwidth to more nearly match the signal bandwidth as it changes over time, whereby output from said filter module (200) is noise-reduced. Other wireless receivers, electronic circuits, and processes for their operation are disclosed.

A method for processing an FM stereo signal. The FM stereo signal is digitized and divided into overlapping blocks, which are transformed into the frequency domain. Individual spectral lines of the difference signal are lowered if these have a higher magnitude than the respective spectral lines of the sum signal. The sum and difference signals are then transformed back.

A right expected value generator generates an expected value of a right channel spectrum from the right channel spectrum. Further, a left expected value generator generates an expected value of a left channel spectrum from the left channel spectrum. Further, a right channel spectrum corrector so corrects a right channel spectrum outputted from a second synthesizer that the right channel spectrum does not exceed the expected value of the right channel spectrum. Moreover, a left channel spectrum corrector so corrects a left channel spectrum outputted from the second synthesizer that the left channel spectrum does not exceed the expected value of the left channel spectrum.
