Last Night’s Homework - REVIEW IOT POLY ENGINEERING 2-2 Last Night’s Homework - REVIEW Radio: Goal: Inform Persuade Entertain Control Manage Educate Source: Sounds and Information Encoder: Devices that convert sound and info into a modulated sine wave (rapidly changing electric current in a wire) http://electronics.howstuffworks.com/radio6.htm Problem: Sine wave contains no information. We need to modulate (vary) it.

Last Night’s Homework - REVIEW IOT POLY ENGINEERING 2-2 Last Night’s Homework - REVIEW Radio: Encoder: Devices that convert sound and information into a modulated sine wave Pulse Modulation: turn the voltage (sine wave) on/off (Morse Code) PM Amplitude Modulation: vary the amplitude (peak-to-peak) voltage http://electronics.howstuffworks.com/radio6.htm AM Frequency Modulation: vary the frequency (speed) FM
