Electronic Signal[edit | edit source]

Information exists in many wave forms generated from different sources. Before information can be processed by electronic devices information needs to be converted to electronic wave forms called signals. Then signals can be processed by electronic devices to amplifying the signal, with volume controlled by adjusting the amplitude of the signal.

Types of electronic signals[edit | edit source]

  • Sine wave
  • Square wave
  • Triangular wave
