The present invention discloses a signal processing apparatus, including: a receiving unit, configured to receive an analog signal; a frequency band adjustment unit, configured to adjust the analog signal to a lowest frequency band when a frequency band of the analog signal received by the receiving unit falls outside the lowest frequency band in multiple preconfigured frequency bands; and a processing unit, configured to process, by using a signal processing channel in the lowest frequency band, the analog signal that has been adjusted to the lowest frequency band by the frequency band adjustment unit. The apparatus provided in the embodiments of the present invention processes signals of different frequency bands by using a processing channel in a lowest frequency band. In this way, only a relatively small quantity of radio-frequency link components are required to implement processing of the signals of the different frequency bands, which reduces a link size of a communications system.
