  • Users can choose from a variety of different filters and sinusoidal inputs.
  • The input and output signals as well as the frequency response of the filter are displayed simultaneously.
  • The mathematical result is hidden until the student wishes to reveal it by pressing the Theoretical Answer button.
  • Various plot options enable the tool to be effectively used as a lecture aid in a classroom environment.
