Source

This component produces a basic waveform. Select the kind of wave you want on the panel on the right. If you create an 'Output' component, and drag its left-hand (input) terminal onto the output terminal of a 'Source component, you will see the waveform in the graph at the bottom. (Press the 'Start' button on the left hand side)

There are several kinds of waveform:

  • Const
    • gives a constant value, specified by amplitude.
  • Saw
    • gives a sawtooth wave, which gradually increases until it reaches its maximum (specified by the amplitude), then suddenly drops back down to the minimum value.
  • Ramp
    • gives a value that ascends and descends linearly between the limits of the amplitude.
  • Sine
    • gives a sinusoidal waveform.
  • Comb
    • gives a periodic transient spike, like the teeth of a comb.
  • Square
    • gives a square wave, which alternates between the maximum and minimum value, as specified by the amplitude.
  • Truncate
    • gives a truncated version of the 'ramp' waveform, such that it reaches a plateau at the maximum and minimum values.
