This circuit simulates the effect of an inductance. Equivalent operational amplifiers can be used, and the power supply must be symmetrical. The circuit is from a 90's Poptronics.
This circuit produces a clef sound when a pulse is applied to its input. The damping effect is...
This circuit can generate signals up to 100 kHz. Found in documentation from the 1980s, it makes...
The crystal used in this oscillator can have frequencies up to 30 MHz or more, depending on the...
