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
Define the term Causality LTI System Any practical LTI system operating in real time must be "causal" which means that its impulse response {h[n]} must satisfy h[n] = 0 for n
Explain graphic adapter and monitor. Video card changes digital output from the computer in an analog video signal and sends the signal by a cable to the monitor also termed a
Explain the effect of a dielectric on the behaviour of a capacitor. If two parallel plates are separated by a distance 'd' (meters) in vacuum and are kept at a potential diffe
