Draw the constellation diagram for the following cases. Find the peak amplitude value for each case and define the type of modulation (ASK, FSK, PSK, or QAM).The numbers in parentheses define the values of I and Q respectively.
a. Two points at (2, 0) and (3, 0)
b. Two points at (3, 0) and (−3, 0)
c. Four points at (2, 2), (−2, 2), (−2, −2), and (2, −2)
d. Two points at (0, 2) and (0, −2)
