EXPERIMENT-1 Performance of Waveform Coding Using PCM
- Generate a sinusoidal waveform with a DC offset so that it takes only positive amplitude value.
- Sample and quantize the signal using an uniform quantizer with number of representation levels L. Vary L. Represent each value using decimal to binary encoder.
- Compute the signal-to-noise ratio in dB.
- Plot the SNR versus number of bits per symbol. Observe that the SNR increases linearly.
