Electronics Demonstrations The following demonstrations use a java applet that simulates electronic circuits. Click on the "Resistors" example for a brief summary of how the applet works. Or you can use the full applet. Basics Ohm's Law Resistors Capacitor Inductor RLC Circuit Voltage Divider Series/Parallel Inductors in Series Inductors in Parallel Capacitors in Series Capacitors in Parallel Thev

This applet is a demonstration of digital filters. Click the "Sound On" checkbox to turn the sound on. The applet starts up with a low-pass filter. It shows the frequency response of the filter, the spectrum of the filtered waveform being played, the waveform itself, and the impulse response of the filter. Click on the response curve to change the cutoff frequency. You can use the popup menus on t

This is a simulation of a ripple tank. It demonstrates waves in two dimensions, including such wave phenomena as interference, diffraction (single slit, double slit, etc.), refraction, resonance, phased arrays, and the Doppler effect. To get started with the applet, just go through the items in the Example menu in the upper right. You can also draw on the screen with the mouse. The predefined setu
