Slide 3 - Core Concepts in A/D Conversion
- Sampling Theorem: States that a continuous signal can be reconstructed if sampled at a rate greater than twice its highest frequency (fs > 2fm).
- Quantization: The process of mapping a continuous range of values to a finite set of discrete values, introducing quantization noise.
- Pulse Code Modulation (PCM): A method used to digitally represent sampled analog signals through sampling, quantizing, and coding.
- Encoding: Converting the quantized digital values into a binary stream for transmission or storage.
