Explore the concept of Quantization Signal-to-Noise Ratio (SNR), a critical parameter in Pulse Code Modulation (PCM) that determines the fidelity of quantized signals in digital communication systems. Core Concepts of Quantization SNR Definition of Quantization SNR Quantization SNR measures the ratio of the power of the quantized signal to the power of the quantization noise introduced during the quantization process. Psnr = Ps / Pq, Or, Psnr = Ps / (Δ² / 12) Where Psnr is the quantization SNR, Ps is the average power of the signal, Pq is the quantization noise power, and Δ is the quantization step size. Importance in PCM In PCM systems, high quantization SNR ensures better signal reconstruction at the receiver, leading to improved quality and performance. Factors Affecting Quantization SNR
