Abstract
Disclosed are an encoder signal sampling method and device. According to the method and device, a data frequency of the encoder is obtained, a clock frequency is determined according to the data frequency, a high-frequency clock signal is generated based on the clock frequency, an input signal of the encoder is sampled based on the high-frequency clock signal to obtain a sampled signal, and finally denoising processing is performed on the sampled signal based on a preset algorithm by a processer.
