Demodulator and demodulation method for demodulating received signals |
摘要 |
The invention relates to a demodulator and also a demodulation method and enables a reliable demodulation even when the intermediate frequency range overlaps the range of the data frequencies of the signal. For this purpose, a rapidly oscillating output signal is generated from the in-phase signal and also the quadrature signal, the sign of which output signal varies in a manner dependent on the product of the signs of the in-phase signal and of the quadrature signal. Either an XOR gate or a multiplier stage may be used in order to generate an output signal of this type.
