Question

Determine the "M" value and number of data bits that can be represented by a single symbol using ASK where the possible amplitude values per symbol can be {0v, +1v, +2v, +3v, +4v, +5v, +6v, +7v}. a. M=2, N=1 bit per symbol b. M=4, N=2 bit per symbol c. M=6, N=3 bit per symbol d. M=8, N=3 bit per symbol

Answer 1

d. M=8, N=3

Step-by-step explanation:

The number of messages (M) that can be sent is 8. The eight messages are the listed amplitude values.

The number of bits per symbol (N) is log2(M) = log2(2^3) = 3.

M=8 messages can be sent, so N=3 bits per symbol.
