Pulse Code Modulation (PCM) Encoding & Decoding of Continuous Signal

Calculations & Observations




Fig.1 PCM Decoded wave (green) & sine wave as input.



Fig.2 Frequency Spectrum of PCM Decoded wave.

The THD is 73.26 % & SINAD is -0.79 dB. The Fundamental frequency is 208.36 Hz & the Fundamental power is 1.00.



Fig.3 Power Spectrum of PCM Decoded wave.

The THD is 70.83 % & SINAD is -1.01 dB. The Fundamental frequency is 205.50 Hz & the fundamental power is 1.34.
