About this subject
Two Part C questions are numericals (AM power/bandwidth; Huffman/Shannon-Fano code efficiency) and two are descriptive (PCM transmitter/receiver; BPSK generation/detection vs QPSK). Learn AM power formulas, PCM bit-rate/SQNR, entropy and coding efficiency, and digital keying basics.
