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
Many circuits, particularly amplifiers, use negative feedback (nfb) in order to function reliably. The nfb changes the performance of the circuit to which it is applied, in most ca
