matlab_frequency_analyse
1.产生一个连续信号,包含低频,中频,高频分量,对其进行采样,进行频谱分析,分别设计三种高通,
低通,带通滤波器对信号进行滤波处理,观察滤波后信号的频谱。
2.采集一段含有噪音的语音信号(可以录制含有噪音的信号,或者录制语音后再加进噪音信号),对其进行
采样和频谱分析,根据分析结果设计出一合适的滤波器滤除噪音信号(1. Produce a continuous signal, including low-frequency, medium frequency, high-frequency components, its sampling, spectral analysis, are designed for three high-pass, low pass, band-pass filter the signal filtering treatment to observe the signal spectrum after filtering. 2. Acquisition section of the speech signal contains noise (can record a signal containing noise, or voice recording, additional noise after the signal), its sampling and spectral analysis, based on an analysis of the results to design a suitable filter to filter out one noise signal)
