Saving a Matlab figure to file using command-line [Matlab]
Once again, this is another example that Matlab does weird things with its figure window. If you use the default function "saveas" it does not save the exact size as it is viewed on your screen....

Echo Filter [Matlab]
An Audio Echo Filter is an FIR filter that repeats a sound after a given Delay attenuating the repetitions. You may test the filter using any input signal (i.e. Matlab "splat" signal). In ... posted by Miguel De Jesus on Dec 1 2010

Zero Crossing Counter [Matlab]
In some DSP applications, it can be very helpful to know how many times your signal has crossed the zero-line (amplitude origin). How is this helpful? Well, zero-crossings can tell you ve... posted by on Jul 9 2011

Adding a Controlled Amount of Noise to a Noise-Free Signal [Matlab]
The following gives two snippets of Matlab code. The first snippet is a function whose inputs are: (1) a real-valued signal, and (2) a desired signal-to-noise ratio (SNR) measured in dB. That 'SNR_Set... posted by Rick Lyons on Jan 3 2012
