QUESTION:
Consider a sinusoidal oscillator formed by connecting an amplifier with a gain of 2 and a second-order bandpass filter in a feedback loop. Find the pole frequency and the center-frequency gain of the filter needed to produce sustained oscillations at 1 kHz.
ANSWER:Step 1 of 5
The following are given by question:
The gain of the amplifier,
Sustained frequency,
We know the feedback factor,
Here, is the sustain frequency, is the pole frequency and pole is denoted by .
