18. Simulate the sigma-delta modulation with Matlab according to the following steps: - Generate the signal $$x(t)=\sin (?t)+0.5\cos \left(\frac{3?t}{2}\right)$$. - Generate $$y(t)=?x(t)dt$$. - Apply delta modulation to $$y(t)$$ at a very high sampling rate. - Apply 1-bit D/A, i.e., construct a pulse train using the outputs of the delta modulator. - Smooth the resulting signal.
