Activity 13.1

Observation of Digital Signal Graph

Method
  • Construct an electric circuit by connecting a 5 V alternating current source, a bulb, a switch and conducting wire.
  • Turn the switch on. If the potential difference between the two ends of the bulb is 5 V, this voltage is considered a high signal (1).
  • Turn the switch off. The potential difference between the two ends of the bulb becomes zero. This is considered a low signal (0).
  • Note the high signals and low signals generated in the circuit as time passes.
  • Record them in a table and draw graphs of potential difference against time.
