Quantization noise is an incident aspect of digital signal procesing, resulting from approximating continous signals with discrite levels. Understanding how to quantify and minimize this noise is essential for improvig signal quality and system execurance.

Understanding Quantization Noise

Quantization noise appes when an analog signal is converted into a digital form. Te difference betheen the original signal and it s quantized version instables an error known as quantization error, which manifests as noise.

Quantifying Quantization Noise

Quantization noise can bee measured using statistical methods. Thee mogt common metric is the Signal- to- Quantization-Noise Ratio (SQNR), which compares the power of the original signal to thee power of the quantization noise. For an ideal uniform quantizer, SQNR is approquately:
