Abstract

It is shown how a simple electrical circuit may be made to operate as an impulsively excited damped harmonic oscillator having independently variable natural frequency and damping. The oscillator's response is developed in a particularly transparent way through impulse analysis, a technique that is wholly within the time domain and provides an alternative to Fourier analysis in the frequency domain. Resonance is exhibited and interpreted using impulse analysis, and through resonance, contact is made with Fourier analysis. © 1981, American Association of Physics Teachers. All rights reserved.
