This device, configured as a delta wave generator ... of the variable frequency cranial electrotherapy stimulation device. As can be seen from the circuit diagram, the heart of the device is a “cheap” ...

Known as quadrature art, the display can be produced with an oscilloscope, a variable frequency square wave generator, and an R-L-C resonant circuit. This can be used to entertain young and ...

The frequency-determining ... If this circuit also had a true triangular-wave output, it would be called a function generator. However, this simple configuration doesn’t have that output waveform.

[Debraj] needed a simple signal generator for a project he was working ... he observed that the PC had good frequency fidelity, though it required an additional DC offset as most cards are built ...

The circuit of Figure 1 generates sinusoids ... 1. This very-low-frequency sine- and square-wave generator requires few components, but provides low-distortion outputs (derived from LTspice ...
