很实用的时频分析工具箱，包括短时傅里叶正反变换等，很好，很强大哦~~分享给大家，包括以下函数的源代码： % sigmerge - Add two signals with given energy ratio in dB. % % Choice of the Instantaneous Amplitude % amexpo1s - Generate one-sided exponential amplitude modulation. % amexpo2s - Generate bilater
function [naf,tau,xi]=ambifunb(x,tau,N,trace); %AMBIFUNB Narrow-band ambiguity function. % [NAF,TAU,XI]=AMBIFUNB(X,TAU,N,TRACE) computes the narrow-band % ambiguity function of a signal X, or the cross-ambiguity % function between two signals.
