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 Magnetic field The area around a magnet is known as the magnetic field and it is in this area that the effects of the magnetic force formed by the magnet can be detected
Consider the circuit shown in Figure with R 0 , (b) the quality factor Q, and (c) the maximum impedance Z m . Comment on the applicability of the universal resonance curve.
Q. Explain from the drain characteristics that a JFET has infinite resistance? When V GS = 0v when a positive voltage Vds has been applied across the channel and the gate
Simulate and compare BER of QPSK system and 4-QAM system without grey coding Eb/No=0.2.4.6.8.10
Pinch off Voltage: The current in N-JFET because of a small voltage V DS is described by: I DSS = (2a) W/L (qN d μ n V DS ) In which 2a = channel thickness
