Test Signals Generation with Matlab Implementation

Generation of test signals for measurements and other purposes.

The present submission is a set of eight Matlab functions that provides a generation of:
1) Sine wave signal
2) Square wave signal
3) Triangular wave signal (incl. Sawtooth)
4) Sweep signal
5) White noise signal
6) Pink noise signal
7) Sinc wave signal (sin(x)/x)
Each function generates a specific type of signal with arbitrary duration, pause, and number of repetitions of the “wave packet” / “wave train” (if any).

Two examples are given to clarify the usage of the functions. For convenience, the input and output arguments are given in the beginning of each function.

The code is based on the theory described in:
