摘要
短时傅里叶和小波变换是信号处理领域的热点研究问题。本文对 2类鸣叫声分别进行短时傅里叶和小波变换 ,以分辨瞬时频率 ,得到了较好的结果。并根据所得结果 ,分析比较了这 2类变换的特点。
ShortTime Fourier Transform and Wavelet Transform are attractive in the community of signal processing In order to analyze and distinguish instantaneous frequency of two types of chirping We use shorttime fourier transform and wavelet transform and get good results Fromthese results the properties of two transforms is given in comparison with each other
