A signal processing circuit and a method for processing an HF input signal are described, having an HF receiver for generating an IF signal on an intermediate frequency from an HF input signal, a frequency divider for generating a signal from the IF signal or a signal derived from the IF signal, with a frequency reduced compared with the intermediate frequency, and a sampling unit for sampling the signal with the reduced frequency by using a sampling frequency, wherein the sampling frequency is smaller than the double intermediate frequency, and wherein the frequency divider divides the intermediate frequency such that the reduced frequency and the sampling frequency are spaced such that the sampling theorem is fulfilled at least for the first odd-numbered harmonic of the signal with the reduced frequency.
