Question: Using Octave, design a composite digital signal using a minimum of 8 0 0 0 samples. The constituent sinusoids are sines having amplitudes of 6

Using Octave, design a composite digital signal using a minimum of 8000 samples. The constituent
sinusoids are sines having amplitudes of 6,2, and 5, respectively. Their respective frequencies are 0.1,
0.15, and 0.25. Plot the composite signal in the frequency domain. Explain in detail the process to
reconstitute the original signal from the plot produced in the frequency domain
