本段程序主要是运用小波去噪对信号进行处理。小波去噪是一种信号处理技术，通过分析信号的频率和时间特性，可以有效地降低信号中的噪声，并提取出信号中的有效信息。在这个程序中，我们使用小波去噪方法对信号进行处理，以提高信号的质量和准确性。通过对信号进行小波去噪，我们可以去除信号中的噪声，使得信号更加清晰和可靠。小波去噪是一种广泛应用于信号处理领域的技术，它在音频处理、图像处理、生物医学信号处理等方面都有着重要的应用价值。
English Description：
This program mainly uses wavelet denoising to process signals. Wavelet denoising is a signal processing technique that can effectively reduce noise in signals and extract effective information by analyzing their frequency and time characteristics. In this program, we use wavelet denoising methods to process the signal to improve its quality and accuracy. By performing wavelet denoising on the signal, we can remove noise from the signal, making it clearer and more reliable. Wavelet denoising is a widely used technology in the field of signal processing, which has important application value in audio processing, image processing, biomedical signal processing, and other fields
