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
any Boolean function can be realized using multiplexer.(true/false).
Suppose that a video signal, having W = 5 MHz, is transmitted via FM with f = 20 MHz. For 1/100 ≤ B/fc ≤ 1/10, determine the bounds on the carrier frequency. Use WFM ∼ = 2( ω + 2W
If a current is passed through a coil, it creates a flux within the coil. Any attempt to change this flux will create a back emf that acts to oppose the change. Consider again
