**using pi to solve for diagram**

Hi, everybody

How can I solve a problem by using MATLAB?

Generate a signal (x[n]) sampled at 8 kHz,

which contains a sum of three sinusoids at frequency of 100 Hz,1,000 Hz, and 2,000 Hz.

Plot this signal for a reasonable number of samples(with MATLAB).

Thank you
