Question (15 marks) A. Write down your date of birth in the following equation. year of birth + month of birth + date of birth and convert the result to a 12-bit binary number e.g. 1948 Feb 04 => 1948 + 02 + 04 = 1954 B. Draw the ASK, FSK and PSK representation of 12-bit number from part A. C. Draw the DPSK representation of the 12-bit number. D. Draw the QPSK output for the 12-bit number. E. List the advantages PSK offer over ASK and FSK modulation formats. F. Using a diagram show the impact on signal bandwidth when using PSK, QPSK and 16-QAM. * 7 B I Question (15 marks) A.
