Introduction
The purpose of analog modulation is to impress an
information-bearing analog waveform onto a carrier for
transmission.
The purpose of digital modulation is to convert an
information-bearing discrete-time symbol sequence into a
continuous-time waveform (perhaps impressed on a carrier).
Key concerns | bandwidth efficiency and implementation
complexity.

These are aected by:
- base band pulse shape
- phase transition characteristics
- envelope
