Question
Frequency of oscillation for three section RC phase shift network is given by ___________ans.
Solution
The frequency of oscillation for a three-section RC phase shift network is given by the formula:
f = 1 / (2π√6RC)
Where:
- f is the frequency of oscillation
- R is the resistance
- C is the capacitance
- π is a mathematical constant whose approximate value is 3.14159
- √6 is the square root of 6
This formula is derived from the general formula for the frequency of oscillation of an RC phase shift oscillator, which is f = 1 / (2πRC√6). In a three-section RC phase shift network, the total phase shift is 180 degrees, which is achieved by three RC sections each contributing 60 degrees. Hence, the √6 in the denominator.
