| 摘要 | Disclosed is a device that detects the presence of several amplitude-modulated high-frequency signals in a sum signal when carrier frequencies are closely adjacent. The sum signal is phase-demodulated by a phase demodulator (156) and is Fourier-transformed by a Fourier transformation unit (157). Based on the Fourier transformation, an evaluation unit (155) determines whether several carrier frequencies are present. | ||||||
