01
Performance Analysis of Digital Modulation Techniques<br>
02
Binary modulation schemes ASK, FSK, PSK
n = 1,
M = 2 (Only Two output conditions are possible)
Baud is equal to the bit rate<br>
03
M-ary Modulation Techniques QPSK, 8-PSK, 18-PSK, QAM, 16-QAM
n > 1
M > 1 (number of output conditions increases)
Minimum bandwidth decreases
Baud rate decreases
Achieves BANDWIDTH COMPRESSION
Less bandwidth is required to propagate a given bit rate
Higher data transmission rates are possible for a given bandwidth<br>
