Quantization Error
Sampling followed by quantization is equivalent to quantization followed by sampling. Figure illustrates a message signal f (t) and its quantized version denoted by fq(t). The difference between fq(t) and f (t) is known as the quantization error εq(t),
εq (t) = fq (t) - f(t)
Theoretically, fq(t) can be recovered in the receiver without error. The recovery of fq(t) can be viewed as the recovery of f (t) with an error (or noise) εq(t) present. For a small δv with a large number of levels, it can be shown that the mean-squared value of εq(t) is given by
When a digital communication system transmits an analog signal processed by a uniform quantizer, the best SNR that can be attained is given by
where S0 and Nq represent the average powers in f (t) and εq(t), respectively. When f (t) fluctuates symmetrically between equal magnitude extremes, i.e., -|f(t)|max ≤ f(t) ≤ |f(t)|max, choosing a sufficiently large number of levels L, the step size δv comes out as
It can be seen that messages with large crest factors will lead to poor performance.
How do I connect a Capacitor on the machine if it has a start mechanism
What is resistivity? Resistivity of a material may be explained as the resistance of the material having unit length and also unit cross sectional area. Unit of it is ohm-m.
Power Diode A power diode is a two terminal, anode a and cathode K and two layer P and N junction devices. A PN junction normally formed by allowing diffusion and epita
Electric flux density (D): Electric flux density is a measurement of electric flux that pass through a unit of plate's area with a coincide angle, that is an area of 1 meter 2
