Relaxation Oscillator as a perfect example of regenerative

[Patrick Chung]

Relaxation Oscillator circuit is a perfect example of regenerative feedback that is special case of positive feedback. Simple and efficient, this circuit is practical for students labs and still applicable in the blinking turn signal on motor vehicles, use in stroboscopes and as the time base in early oscilloscopes and television receivers.
