Full Wave Rectifier Simulation ver.1

Posted by Circuit Negma on April 12, 2006


fullWave.cir Full Wave Rectifier Simulation ver.1

* VS is the input for this circuit.  Say, it has a phasor amplitude of 1 volt in
* the F-domain and a sine waveform in the time domain, of 120 volt at 60 Hz.
* The following combination, independent, voltage source statement
* gives both the F and T domain specification.
