matlab中调幅信号的源代码及不同参量信号的程序 function y = amgauss(N,t0,T); %AMGAUSS Generate gaussian amplitude modulation. % Y=AMGAUSS(N,T0,T) generates a gaussian amplitude modulation % centered on a time T0, and with a spread proportional to T. % This modulation is scaled such that Y(T0)=1 % and Y(T0+T/2) and Y(T0-T/2) are approximately equal to 0.5 . % % N : number of points. % T0 : time center (default : N/2). % T : time spreading (default : 2*sqrt(N)). % Y : signal.
