Assignment Questions
Part –A
Q1. Given the bit pattern 11010011, encode this data using ASK, FSK and PSK (i.e., draw the
waveform that represents each ‘1’ or ‘0’ in a neat diagram). In the diagram, label the amplitude
values used in ASK, frequency values used in BFSK (binary FSK because there are only 0 and 1
in the data), as well as the phase values used in BPSK (binary PSK).
(Hint: see slides on ASK, FSK & PSK in Lecture 5).
