Modulation
?odification of a carrier wave’s fundamental characteristics in order to encode information
- Carrier wave: Basic sound wave transmitted through the circuit (provides a base which we can deviate)
?asic ways to modulate a carrier wave:
- Amplitude Modulation (AM)
- Also known as Amplitude Shift Keying (ASK)
- Frequency Modulation (FM)
- Also known as Frequency Shift Keying (FSK)
- Phase Modulation (PM)
- Also known as Phase Shift Keying (PSK)
