Q. Free running multivibrator is also called as

A
Voltage control oscillator
B
Stable multivibrator
C
Pulse stretcher
D
None of the above
Solution:

Free running multivibrator operates at a frequency which is determined by an external tuning capacitor and a resistor. On applying a dc control voltage the frequency can be shifted on either sides. This frequency deviation is directly proportional to the dc control voltage and hence it is called as ?oltage controlled oscillator?/p>
