Resource Overview
This program performs analog signal digitization through PCM (Pulse Code Modulation), converting sampled values into 8-bit PCM codes, which represents the predominant encoding methodology in modern voice coding systems
Detailed Documentation
This program implements analog signal digitization using Pulse Code Modulation (PCM) methodology. PCM is a fundamental technique for converting analog signals to digital format by quantizing sampled values into 8-bit binary codes. The implementation typically involves three key stages: sampling at Nyquist rate, quantization using uniform or non-uniform quantizers, and binary encoding. Modern voice coding systems predominantly employ this approach due to its effectiveness in preserving speech signal quality while minimizing data transmission overhead. The 8-bit resolution provides 256 quantization levels, balancing between signal fidelity and computational efficiency for real-time audio processing applications.
