Answer:A
At what condition the output signal can be continuously obtained from input signal?
A. When the product of input voltage and feedback voltage is equal to 1 B. When the product of amplifier gain and transfer ratio is equal to 1 C. When the product of feedback voltage and transfer ratio is equal to 1 D. When the product of amplifier gain and input voltage is equal to 1
Explanation: When Aß=1, the feedback signal will be equal to the input signal. At this condition, the circuit will continue to provide output, even if the external signal is disconnected. This is because the amplifier cannot distinguish between external signal and signal from the feedback circuit. Thus, output signal is continuously obtained. 3. An oscillator is a type of
