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
For the 3-bit 2 n -R D/A converter of Figure, calculate the analog output voltage when the input is (a) 100, and (b) 010. Solution a. For the binary input 100, switches con
