## Yes, your assumption is correct. In PSK or phase shift keying, the number indicates the number of different phase shifts that are used to represent binary patterns. In 8PSK, there are eight different phase shifts, and each phase shift represents one of the eight patterns of three bits. Likewise, in 256PSK, there are 256 different phase shifts, and each phase shift represents one of the 256 patterns of eight bits.

To confirm whether you are right, you can use the formula 2^n to calculate the total number of patterns for a given number of bits. In this case, n represents the number of bits. For example, 2^3 equals 8, which matches the number of patterns in 8PSK. Similarly, 2^8 equals 256, which matches the number of patterns in 256PSK.

So, based on the pattern of powers of 2, your assumption is correct.
