| overtone |
The Inductorless 3rd-0vertone circuit is similar to the fundamental frequency circuit except the feedback resistor value is made much smaller (typical value varies between 2 kQ to 6 kQ). In this case, the component of inductive admittance due to the resistor is greater than the admittance of the loading capacitance at the fundamental frequency, thereby preventing oscillation at the fundamental frequency. ...
