How sustained oscillation can be achieved?
A. Maintaining |Aß| slightly greater than unity
B. Maintaining |Aß| equal to unity
C. Due to non-linearity of transistor
D. Due to use of feedback network
Answer:C
How sustained oscillation can be achieved?
A. Maintaining |Aß| slightly greater than unity B. Maintaining |Aß| equal to unity C. Due to non-linearity of transistor D. Due to use of feedback network
Explanation: When |Aß| is kept slightly greater than unity the signal, however, cannot go on increasing and get limited due to non-linearity of the device (that is transistor enters into saturation). Thus, it is the non-linearity of the transistor because of which the sustained oscillation can be achieved. [/expand]
