convolutiondemo
线性非时变系统的卷积的demo,有助于对卷积的理解。欢迎大家分享之(As one would learn in a basic signal processing/controls/dynamical systems class, the multiplication by an LTI transfer function F(s) in the frequency domain is the same operation as convolution with f(t) in the time domaininformation hiding that is known as self-embedding. In essence, the process embeds a copy of the media into itself, of course it goes without saying that the copy has to be encrypted before the embedding takes place. The program is written purely in MATLAB with some scripts in PHP and HTML.

simulateQSNR
Determine the SNR for a quadrature delta-sigma modulator using simulations.
The modulator is described by a noise transfer function (ntf)
and the number of quantizer levels (nlev).
The ntf/stf may be given in ABCD form.
The band of interest is defined by the oversampling ratio (R)
and the center frequency (f0).
