automobile electronics
Automobile Electronics
  • Previously all mechanical systems have become increasingly electronic
  • Over the past few years, for example, the automobile has begun to use more computers (microcontrollers)
  • How many microcontrollers are typically found in a modern automobile?

impedance
Impedance
  • Definition: a general measure of how a circuit affects the current through it.
  • Impedance = resistance + reactance
  • Impedance is used to refer to the behavior of circuits with resistors, capacitors and other components.
  • In a resistive circuit, impedance=resistance.
equipment impedances
Equipment Impedances
  • Each measuring device changes the circuit when you use it.
  • The impedance of the device helps you understand how much.
  • Device Impedances
    • Function Generator: 50 ohms
    • ‘Scope: 1Meg ohms
    • DMM (DC voltage): 10Meg ohms
    • DMM (AC voltage): 1Meg ohms
    • DMM (DC current): 5 ohms (negligible)
