Explain Quantizing Analog Signals?
A common analog-to-digital conversion pipeline contains a spectrum limiter (a simple low-pass or bandpass filter), a sample and hold circuit, a quantizer, and a digitizer. Quantization inevitably introduces errors, although errors can be decreased by:
a) Increasing the number of quantization levels
b) Introducing non-uniform quantization
