1.	Measure of sensitivity of crystal oscillator output frequency to supply voltage is called ___________(a) Frequency pulling(b) Frequency ratio(c) Output ratio(d) Frequency pushingThis question was posed to me by my school teacher while I was bunking the class.Asked question is from Crystal Oscillator-2 in chapter Oscillators of Analog Circuits
Answer» The correct answer is (d) Frequency pushing Explanation: Every oscillator NEEDS a supply and the operating frequency is DEPENDENT on that voltage. As the DC supply changes, the output frequency may ALSO change and this is called frequency pushing. Frequency pulling is the change in output frequency DUE to change in APPLIED load.
