Question
A second condition for oscillation is 1 pointno gain around the feedback loopa gain of 1 around the feedback loopthe attenuation of the feedback circuit must be one-thirdthe feedback circuit must be capacitive
Solution
The second condition for oscillation is a gain of 1 around the feedback loop. This means that the total phase shift around the loop is 0 or 360 degrees and the magnitude of the product of the gain and the feedback factor is 1. This condition ensures that the oscillations sustain over time.
