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
Q. Explain about Synchronous machines? Large ac power networks operating at a constant frequency of 60 Hz in the United States (50 Hz in Europe) rely almost exclusively on sync
Consider a three-phase induction motor with a normal torque-speed characteristic. Neglecting the effects of stator resistance and leakage reactance, discuss the approximate effect
i v characteristics of practical current source
Q. For the low-pass filter configuration of Figure, with R i = R f = 1M, calculate C f such that the 3-dB point is at 1 kHz.
Consider the analog averager where x(t) is the input and y(t) is the output. (a) Find the impulse response h(t) of the average. Is this system causal? (b) Let x(t)
Mathematical relationship between the induced e.m.f and the network Faraday noted that the e.m.f induced in a loop is proportional to the rate of change of magnetic flux by it:

Q. Explain Working of Liquid-crystal display? This display needs only microwatts of power (over a thousand times less than a LED) and is used in such devices as electronic wris
Q. Dynamic Response of Control Systems? The existence of transients (and associated oscillations) is a characteristic of systems that possess energy-storage elements and that a
