Abstract:
In an FSK receiver according to the present invention, a correction operation for a DC offset component is performed based on a maximum value and a minimum value of a demodulation signal. If a difference between the maximum and minimum values is less than a predetermined threshold value TH1, the correction operation is halted. Thus, the FSK receiver can rapidly perform an appropriate offset removal from a multi-level FSK signal.
