Analog Electronics - Engineering
Q1: The input voltage for starting oscillations in an oscillator is caused byA negative feedback
B
positive feedback
C
noise voltage in resistors
D
a special generator
ANS:C - noise voltage in resistors The amplifier in the oscillator amplifies the noise voltages. However phase shift around the closed loop is zero at only one frequency. Therefore, only this frequency appears at output. |
