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
Operation of heterodyne wave analyzer with block diagram
Explain Einstein relation. Einstein relation: There exists a significant relation between the diffusion constant and the mobility. It is termed as the Einstein relation and
Q. Use of N-channel JFET? Generally, N-channel JFETs are more commonly used than P-channel. With no voltage applied between gate and source, the channel is a wide-open path for
Q. Show Maximum Common-Mode Input Voltage of amplifier? This is the maximum voltage that the two inputs can be raised above ground potential before the op amp becomes nonlinear
Draw the re-model for the circuit given in figure and calculate: a). The input impedance (β=100), b). The output impedance (r0 = 50 kΩ) and c). The mid-band collector-base
1. A very narrow laser beam in air is shone into a sphere of solid glass that has a uniform refractive index n>1 and radius ? . The beam makes an angle a in air with the normal to
Q. Write a note on the application of emitter-follower? An emitter follower can serve as a buffer for a voltage source. The voltage divider at left is a poor voltage source bec
Q. (a) An audio amplifier with R i = 10 k, R o = 0, and ¯A(ω), as shown in Figure (a), is used in the circuit shown in Figure with R S = 1 k,R L = 16 , and C = 0.2 µF. Sk
Q. Consider the inverting integrator circuit shown in Figure. Let C = 0.4µF and R = 0.1M. Sketch v o for a period of 0.5 s after the application of a constant input of 2 V at the
Q. Draw and explain Colpitts oscillator? Colpitt's oscillator is a superb circuit which is used widely in commercial signal generations of frequency of 100 Mhz . It consists o
