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
A. Feedforward amplifier
B. Feedback amplifier
C. Waveform amplifier
D. RC amplifier
Answer:A
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
A. Feedforward amplifier B. Feedback amplifier C. Waveform amplifier D. RC amplifier
Explanation: An oscillation is a type of feedback amplifier in which a part of output is fed back to the input via a feedback circuit. 4. Find the basic structure of feedback oscillator.
