Equivalent

This very simple m-function computes cross spectrum, coherence and phase at the same time. The input parameters are equivalent to pwelch.n or csd.m in MATLAB and use csd.m in the singal toolbox.It's very simple but useful for engineers.

The AWGN Channel Block in the Communications Blockset lets you specify SNR in several ways, including Eb/No. Sometimes people want to use a more itemized way of specifying the SNR, like the itemization found in a link budget.These two models show how to create equivalent implementations of a...

FASTRMS Instantaneous root-mean-square (RMS) power via convolution.FASTRMS(X), when X is a vector, is the time-varying RMS power of X, computed using a 5-point rectangular window centered at each point in the signal. The output is the same size as X and contains, for each point in X, an estimate...
