a second front-end switch module, configured to receive the fourth signal and select a target second filter from the plurality of second filters according to the fourth signal;
the target second filter is used for receiving the fourth signal and filtering the fourth signal to obtain a seventh signal;
the radio frequency processor is further configured to receive the seventh signal and process the seventh signal.
5. The system according to any of claims 2 to 4, wherein the combiner is in particular configured to split the received signal into at least two of a high frequency band signal, an intermediate frequency band signal, and a low frequency band signal.
6. The system of claim 3, wherein the combiner is further configured to divide and filter the received signal to obtain an eighth signal, the eighth signal having a different frequency than the first signal and the fourth signal;
the system further comprises:
the third low-noise amplification processor is used for receiving the eighth signal and amplifying the eighth signal to obtain a ninth signal;
a third front-end switch module for receiving the ninth signal and selecting a target third filter from a plurality of third filters according to the ninth signal;
the target third filter is configured to receive the ninth signal and perform filtering processing on the ninth signal to obtain a tenth signal;
the radio frequency processor is further configured to receive the tenth signal and process the tenth signal.
7. The system as recited in claim 6,
the combiner is specifically configured to divide the received signal into a high-frequency band signal, an intermediate-frequency band signal, and a low-frequency band signal.
8. The system according to any of claims 1-7, wherein the first front-end switch module is specifically configured to select the target first filter from the plurality of first filters according to a signal frequency of the second signal.
9. The system of any of claims 1-8, wherein the first filter is a surface acoustic wave filter.
10. An electronic device, characterized in that the electronic device comprises a signal processing system according to any one of claims 1 to 9.
