This circuit generates sine low-frequency signals. The frequency depends on the twin-T network. Refer to the section Mathematics for Electronics to calculations. The potentiometer is used to adjust the correct point of oscillation. A time interval must be expected to the circuit begins to run. Any general purpose NPN transistor, as the BC548 also cam be used.
