Study Notes

Analog to Digital Conversion

The process of converting analog signals to digital signals is called Pulse Code Modulation (PCM).

Pulse Code Modulation (PCM) Steps

The three steps involved in Pulse Code Modulation (PCM) are:
- Sampling: selecting data points to create the digital data.
- Quantizing: assigning a digital code to each sampled value.
- Coding: converting the quantized values into a binary code.

Quantizing in PCM

Quantizing in Pulse Code Modulation (PCM) involves assigning a digital code to each sampled value.

Applications of PCM

One common application that uses Pulse Code Modulation (PCM) is Compact Disc (CD) audio recording.
