More Information
Summary:A signal processing method, device and system are provided. A fitting amplitude of an input signal is acquired by performing fitting on the input signal according to a predetermined fitting model. A determination result about whether to apply a gain on the input signal is determined based on the fitting amplitude, and a gain signal is obtained based on the determination result. A delay signal acquired by delaying the input signal is processed based on the gain signal, to obtain an output signal. With the signal processing device and system, a simple structure and a small calculation amount are achieved, and the signal processing efficiency and the signal processing effect are improved.
