Title:
SIGNAL PROCESSING SYSTEM AND METHOD
Document Type and Number:
WIPO Patent Application WO/2023/011288
Kind Code:
A1
Abstract:
Disclosed in the embodiments of the present application are a signal processing system and method. The system comprises a first signal amplification module, a first filtering module, an amplification/attenuation module, a frequency mixing module and an intermediate-frequency filtering module, wherein the first signal amplification module receives a signal under test, and performs amplification processing on the signal under test, so as to obtain an amplification signal under test; the first filtering module performs filtering processing on the amplification signal under test, so as to obtain a filtering signal under test; the amplification/attenuation module performs amplification/attenuation processing on the filtering signal under test, so as to obtain an amplification/attenuation signal under test; the frequency mixing module performs frequency mixing processing on the amplification/attenuation signal under test, so as to obtain a frequency mixing signal under test; and the intermediate-frequency filtering module performs intermediate-frequency filtering processing on the frequency mixing signal under test, so as to obtain an intermediate-frequency signal under test.
