Huffman Coding
The objective of this problem is to design Huffman codes using MATLAB. The discrete memory less source output is generated from the alphabet
with the corresponding probabilities
1. Determine the entropy of the source.
2. Design a Huffman code and sketch the corresponding code tree. Specify the code words for the six symbols in the alphabet.
3. Determine the efficiency of the Huffman code designed in Part 2.
4. Design a Huffman code for the source sequences of length 2 and sketch the code word tree. Specify the code words for the symbols of length 2 and determine the efficiency of the code. Compare the efficiency for length 2 sequences with that for length 1.
The 32 X 6 ROM together with the 2^0 line converts a 6-bit binary number to its corresponding 2-digit BCD number. For example, binary 100001 converts to BCD 011 0011 (decimal 33). Specify the truth table for the ROM.
show that carrier reinsertion can be used to demodulate a SSB signal. Illustrate the effect of using a demodulation carrier with insufficient amplitude when using the carrier reinsertion technique.
Suppose that the number of customers entering a department store in a day is a random variable with mean of 50 customers/day. Suppose that the amounts of money spent by each one of these customers are statistically independent.
Design a 4-bit binary incrementer using HALF-ADDERS as building blocks. The circuits implements A+1=S where A and S are 4-bit binary numbrers. The circuit has 4 inputs A3A2A1A0 and 5 outputs : S3S2S1S0 and overflow C4. Draw the circuit diagram wit..
