Description should include
- characteristics of modulation—the combination of a carrier signal of periodic waveform (i.e., baseband) with a data information signal (i.e., passband) to be transmitted
- various methods of achieving modulation—frequency modulation (FM), amplitude modulation (AM), phase modulation, phase-shift keying, digital modulation method (i.e., modems)
- how pulse modulation methods (pulse width modulation [PWM]) are used to exchange information and control servos.
Process/Skill Questions:
- What are the types of modulation, and how do they differ?
- What electronic circuitry is necessary to transmit and receive modulation?
- What are the applications of modulation circuits?
