2071 Chaitra (Q) Explain the importance of source coding in digital communication systems. A discrete memoryless source emits four symbols with probabilities p= {0.125,0.125,0.25,0.5}. If the output symbols are encoded using Shannon Fano Code, Find the coding Efficiency and Compare the coding efficiency with that of BCD code.
by 11 Source coding is the process of conversion of the output of the DMS into a sequence of the binary symbol (BCD). It helps in the …
