005_AM_Source : Amplitude Modulated Source
Minimum Versions: SmartSpice 4.6.5.R
The input deck shows how you can setup a single voltage source element to have a Amplitude Modulated sinewave output.
A plot of the waveform shows the low-frequency modulation of the higher frequency sinewave signal. The example facilitates how you can study bursts of a signal into your circuit and the circuit's subsequent recovery/stability.
