IOT POLY ENGINEERING 2-2 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) Sine wave contains no information. We need to modulate (vary) it. Problem: Last Night’s Homework - REVIEW

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

IOT POLY ENGINEERING 2-2 Last Night’s Homework - REVIEW Radio: Goal: Inform Persuade Entertain Control Manage Educate Source: Sounds and Information Encoder: Devices convert sound and info into modulated sine waves Transmitter: Antennas radiate the radio waves into air (medium) Receiver: Antennas capture the radio waves from air Decoder: Devices convert radio waves back into sounds and data [Storage: Recording devices store sounds and data for playback] [Retrieval: Stored data can be accessed and played] Destination: Consumers’ ears and eyes
