Electronic Signals

Quick-jump to AC and DC Signals

Purpose of Electronic Signals

• Electronic Signals move information like cars move passenger down the highway
• Signals allow devices (e.g. sensors, or switches) to communicate with Control Modules
  • Such communication can be completed via simple Relays
  • Other times, the communication requires a complicated processor
• Signals and the modules perform or request (through more signaling) other functions to be carried out

Example of Signals

• A Signal can inform the Climate Control the outside air temperature.
• A Signal can inform the brake lights the right time to illuminate.
• A Signal can inform the DME to enable ABS due to rain.

The use of electronic signals goes far beyond the basic application of electron flow to some components. Electronic signals enables (or allow) complex information to be passed from one component to another.

The data (input or output) is exchanged through various forms such is changing voltages, resistance, current or frequency modulation.

Electronic Signals are divided into two (2) main groups. There is AC Type Signals and DC Type Signals.
