Consider speech signal x(t), which has the magnitude spectrum X(f)= rect(f/100).

Sketch the magnitude spectrum of the sampled x(t) resulted by conducting natural sampling with the sampling freq 180Hz. Comment on your result.

Discuss how to perform digital to analog conversion to recover x(t). Is it possible to fully recover x(t) without distortion? Justify your answer.
