Patent ID: 6922555

Claim:
A receiver for receiving an angle modulated radio frequency signal, said receiver comprising: first down-conversion means for down-converting said received angle modulated radio frequency signal to an intermediate frequency angle modulated signal; limiting means for generating a limited signal from said intermediate frequency angle modulated signal; second down-conversion means for down-converting said limited signal to an in-phase and a quadrature second down-conversion means for down converting said limited signal to an in-phase and a quadrature zero intermediate frequency signal; low pass interpolation filtering means for interpolating said in-phase and quadrature zero intermediate frequency signals; and demodulation means for producing a demodulated signal from said interpolated in-phase and quadrature zero intermediate frequency signals, said intermediate frequency being chosen such that said limited signal comprises an unwanted signal at twice said intermediate frequency that acts as a noise spreading signal for spectrally spreading of quantization noise generated by said limiting means, and a cut-off frequency of said low pass interpolation filtering means being chosen such that said unwanted signal and said spread quantization noise are suppressed.
