摘要
在工程信号处理中,频率是一个非常重要的参数。分析了传统的频率求解方法,并就信号频率发生较小变化的识别问题提出了一种基于小波变换的算法。对于信号处理和一些利用频率进行诊断的工程问题具有一定的参考价值。
Frequency is a very important parameter in the engineering signal processing. The traditional methods for frequency solving are analysed and a new algorithm for identification of frequency's indistinctive change based on wavelet transform is put forward. It is of reference value for signal processing and diagnostic problem in which the frequency estimation plays an important role.
