Three-Way Voltage Summer
 National Instruments Corporation 1-45 Multisim Component Reference Guide
The summer may be used to illustrate the result of adding harmonically related sine wave
components which make up a complex waveform (the first three terms in the Fourier
expression defining the waveform).
In the example, a fundamental frequency of 60 Hz. and the third and fifth harmonics (in
phase) may be progressively added to illustrate the basic makeup of a square wave.
Amplitude and phase of any of the signals may be varied to experiment further.
Caution The switches should not be operated while a solution is in
progress. This will result in solution error messages. Allow the
solution to pause (or pause it by clicking on the solution switch).
Operate a switch to add the desired harmonic, and then solve the
circuit again.
