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).
