3. 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

4. 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

5. 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

7. IOT POLY ENGINEERING 2-2 – Assignment should be set up similar to our example. – Also, include a labeled diagram. LETTER THIS ASSIGNMENT 1.Classify the following as 2.Radio, T.V., Cell Phone, Internet, GPS, Remote Control 3.Explain your classification. 4.Analyze the components of each of those 6 communication technologies, including the goal, source, encoder, transmitter, receiver, decoder, storage, retrieval, and destination. Last Night’s Homework - REMINDER 1 Info sheet required for each of the required 6 communication technologies: Radio, T.V., Cell Phone, Internet, GPS, Remote Control

8. IOT POLY ENGINEERING 2-2 What it does: Identifies clues to water Characterizes rocks and soils Characterizes climate Communication connections: Human to Machine Machine to Machine Machine to Human Examples?

9. 1 Classroom Exploration Robot (CER): – No sight; only sound recognition and mobility 2 Mission Control (MC): – Cannot see playing field, only a map – Communicate to CER using specific directives 1 Communication Transmitter (CT): – Transmit communication between CER and MC [1 Spy Satellite (SS):] [– Follow another team’s CT to ensure no cheating] Players (4 or 5): IOT POLY ENGINEERING Objective: Be the first team to successfully create your required 3 mechanisms and deposit them where required.
