Abstract
A method of demodulation includes determining samples of a modulated analogue audio signal; determining at least one distorted sample of the samples depending on the signal quality of the modulated analogue audio signal; and replacing the distorted sample.
Claims32
A method of demodulation, comprising:
- determining samples of a modulated analogue audio signal;
- detecting at least one distorted sample of said samples depending on a signal quality of said modulated analogue audio signal;
- and
- replacing said distorted sample;
- wherein
- when the distorted sample is detected, a previous sample occurring N number of samples before the distorted sample, N being a positive integer value and greater than 1, is repeated and the distorted sample is replaced by the previous sample.

A receiver, comprising:
- a first signal processor adapted to determine samples of a modulated analogue audio signal, and further adapted to determine a signal quality of said modulated analogue audio signal;
- a second signal processor adapted to determine at least one distorted sample of said samples depending on said signal quality, and further adapted to replace said distorted sample;
- wherein
- said second signal processor comprises a series of N storage units adapted to store and output a time-shifted sequence of samples, with N being an integer value greater 1.
