Q. What do you mean by Source Encoding?
After the quantization of message samples, the digital system will then code each quantized sample into a sequence of binary digits (bits) 0 and 1. Using the natural binary code is a simple approach. For a code with Nb bits, integers N (from 0 to 2Nb - 1) are represented by a sequence of digits, bN ,bN -1,...,b2,b1, such that
Note that b1 is known as the least signi?cant bit (LSB), and bNb as the most signi?cant bit (MSB).
Since a natural binary code of Nb bits can encode Lb = 2Nb levels, it follows that
L ≤ Lb= 2Nb
if L levels span the message variations. For example, in Figure (b), Nb = 3 and L = 8; the binary code word 010 represents 0(23-1) + 1(21) + 0(20) = 2 V, and 110 represents 1(23-1) + 1(21) + 0(20) = 6 V. Thus, binary code words with Nb = 3 are shown in Figure (b).
Q. An integrator as shown in Figure is to be designed to solve dy(t) / dt + 2000y (t) = 0 with y(0) = 5. If R i is chosen to be 10 k, find C f .
Determine the equivalent winding resistance: A 50 kVA, 2200/110 V, 50 HZ' transformer contain an HV winding resistance of 0.15 Ω and a leakage reactance of 0.45 Ω. The LV wind
Critical Rate of Rise of Current The maximum rate of increase of current during on state which the SCR can tolerate is called the critical rate of rise of current f
Circuits, which provide sinusoidal waveforms, are but useful in themselves and form the basis of many other circuits, such as square and triangular waveform generators, and clocks.
The output port of the one-port is defined by terminals A and B. Given: R 1 = 10 k_, R 2 = 20 k_, R 3 = 10 k_, and R 4 = 10 k_ V 1 = 20 V and I1 = 0.8 mA a) Find the T
