Operating Modes of Dynamic Power Supply Transmitter Amplifiers

Any amplifier operated with a varying supply voltage is actually a three-port circuit, having two inputs and one output. When an amplifier is characterized as a three-port for dynamic supply voltage operation, three separate operating modes...

Wave on a String Demo


Michael Dubson/Univ. of Colorado

This interactive demo allows you to experiment with waves and reflections under various conditions. The demonstration shows mechanical waves but the concepts are analogous to EM waves on transmission lines.

Watch a string vibrate in slow motion. Wiggle the end of the string and make waves, or adjust the frequency and amplitude of an oscillator. Adjust the damping and tension. The end can be fixed, loose, or open.
