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 ...

If you are feeling brave, you might try to replace the ramp generator with a variation on the triangle wave circuit. There are many other changes you might try, such as replacing the diode with ...

The simplified block circuit shows IC1 operating as a square-wave generator with frequency determined ... The frequency of the simultaneous square, triangle, and sine waveforms can be switched ...

This circuit, a modification of a function-generator circuit ... well at low voltages (i.e., less than ±12 V). Apply a triangle wave of about ±4 V (8 V p-p) to the input at R1 and observe ...
