Natural Sampling

Code computes PSD of Pam Signal, Reconstruction of PAM SIgnal and Distortion of Demodulated signal

Code computes Time domain and frequency domain plot of input signal,
Pam Signal, Recovered Signal. Code also Computes Distortion
%%%%%% PSD Of PAM Signal is stored in an array Power_PAM that has powers of PAM signal stored in [Pfm Pfs-fm pfs+fm .........] with units watts. Power_PAM_dbw stores PSD of PAM in dBw.

Aim is to to see the effect of duty cycle and sampling frequency of sampling signal on demodulated signal. It also aims at seeing the effect of order of the reconstruction filter.
