Abstract
A signal processing circuit for dynamically processing an analog signal. The signal processing circuit may include a detection module and a fluctuation filter module. The detection module may be configured to detect a voltage of a first sub-signal of a first frequency band of the analog signal in real time and transmit a first control signal when the voltage of the first sub-signal is out of a first preset voltage range. The fluctuation filter module may be configured to remove a second sub-signal of a second frequency band of the analog signal from the analog signal upon receiving the first control signal. The second frequency band may cover the first frequency band.
