How many different phases would an 8PSK modulated signal wit

How many different phases would an 8-PSK modulated signal with the following constellation diagram have? 3 4 16 1 256 8

Solution

ANSWER - 8

generally 8 PSK modulator uses one complexd value for three input data. There are eight possible symbols configuration in 8-PSK that can be transmitted for 8 different phases and each of phase difference of 45 degrees.
