This is a brief, handy DSP Toolkit authored purely in MatLab that provides for the basic, introductory DSP functions like convolution, fast convolution, sampling, quantization, Fourier transforms and their relatives. See the contents file for a full list of functions. If used with prudence , I think its ideal for DSP lab exercise design.

Version Published Release Notes

I have corrected function my_CTFT1.m by removing the imaging artifacts out of interval [-pi*Fs, pi*Fs].


I forgot to exclude some obsolete files.


I have included the 2 new signal CTFT approximation functions: my_CTFT and my_CTFT1. The first one makes use of the matlab provided fft.m function and therefore is much faster. The later makes use of the definition formula and is more intuitive.
