How oscillators work? Answered
Why oscillators like wien bridge oscillator or RC phase shift oscillator gives only sinusoidal waves instead of triangle waves or square waves of particular frequency. Please dont explain about multi-vibrators .
Also please say how to differentiate between low frequency oscillator and high frequency oscillator. By using any value of R(resistance) and C(capacitance) i will be able to get any frequency(high or low) by substituting in respective formula. But what makes one to judge a oscillator as high frequency or low frequency.
