Pulse Code Modulation (PCM) Basics

Submitted by Steve on Sun, 06/07/2008 - 5:02pm

A simple example of sampling a sine wave at different sampling rates, and different number of levels. You can see how increasing the sampling rate and number of levels produces a digital waveform closer to the continuous sine wave. But in practice this comes at the expense of an increased required data rate to send the digital data.

Frequency: 1Hz
Samples: 50 per second
