Draw the constellation diagram for each of the following:

a) ASK with four different amplitudes 0, V/3, 2V/3,V

b) PSK with a peak amplitude value V and the phase angle selected according to 3 bits of data

c) QPSK with a peak amplitude value V

d) 16-QAM For each case, state also the bit rate when the signaling rate is 1500 Mbaud.
