Single Frequency Oscillator or SFO

Single Frequency Oscillator or SFO is made up of class A Transistor Amplifier with feedback circuit consists of parallel LC Tuned circuit or a RC phase shift of 180^o

Characteristics

Parallel LC Tuned Circuit

The Oscillating Frequency is calculated by

$f=\frac{1}{2\pi }\sqrt{\frac{1}{lC}}$

RC phase shift of 180^o

The Oscillating Frequency is calculated by

$f=\frac{1}{2\pi }\frac{1}{RC}\frac{1}{Tan\mathrm{\Theta }}$
