- Convert the binary sequence to a sequence of symbols with values 0,1,2, or 3.
- Map the sequence of symbols to a sequence of amplitude levels -3,-1, +1, +3.
- Multiply the sequence of amplitude levels by a sine or cosine wave at the appropriate carrier frequency.
- Plot all of the results versus time.
