The triangle wave generator circuit can generate signals with frequencies up to 300 kHz. With the component values presented in the diagram the output wave frequency is 38 kHz. The frequency can be ...

The circuit is a triangle waveform generator that uses as few parts as possible. A 555 timer IC, 2 resistors and two capacitors make the triangle wave. The IC is connected in a 50% duty-cycle astable ...

This all-analog circuit provides ... to implement a triple-waveform generator at one of two selectable frequencies. 2. The frequency of the simultaneous square, triangle, and sine waveforms ...
