a.
2
b.
1/3
c.
3
d.
1/2
Solution
The gain of the feedback network for a Wein Bridge Oscillator tuned at 1KHz is 1/3. So, the correct answer is b. 1/3.
Here's a step-by-step explanation:
-
The Wein Bridge Oscillator is a type of oscillator which is based on an operational amplifier (op-amp). It is used to generate sinusoidal waveforms.
-
The frequency of oscillation for a Wein Bridge Oscillator is given by the formula: f = 1/(2πRC), where R and C are the resistance and capacitance in the circuit respectively. In this case, the oscillator is tuned at 1KHz, but the frequency doesn't affect the gain of the feedback network.
-
The gain of the feedback network in a Wein Bridge Oscillator is always 1/3. This is because the feedback network is a voltage divider that takes a fraction of the output voltage and feeds it back to the input. The fraction is determined by the resistors in the feedback network, and in the case of a Wein Bridge Oscillator, it is always 1/3.
-
Therefore, regardless of the frequency at which
