What are you conclusions about the phase relationship between the driver and the oscillator below and above resonance?
For small frequency of forced oscillation , the phase angle between the forced oscillator and driver is nearly zero . As the driving frequency increases the phase angle increases and is equal is PI/2 ,when both the frequencies (frequency of force and frequency of system for oscillation) are equal. For very large frequency of driver , they are out of phase.
Why did Nikola Tesla invent the Tesla Oscillator?
Tesla's electro-mechanical oscillator is a mechanical oscillator conceived of and invented by Nikola Tesla in 1898. Tesla's oscillator or "Earthquake machine" is a mechanical oscillator that was invented by Nikola Tesla in the year of 1898. the original oscillator that Tesla designed and tested was small , almost seven inches long , and it weighed about one or two pounds. This small device was designed to be powered by steam pressure, only five pounds of air pressure against a special pneumatic piston device was used to operate it. The concept of Tesla oscillator is purely mechanical. In 1898 Tesla had a lab on Huston Street in New York. It was claimed that while Tesla was experimenting his mechanical oscillator he generated a resonance of several buildings near his house causing complaints to the police, as the oscillator speed increased he hit the resonance frequency of his own house. belatedly Tesla realized that he was in danger and has was forced to use a sledge hammer to breakdown the oscillator and stop the experiment , just as the shocked police arrived .
What is the use of local oscillator?
Trasmitting stations have their own transmitting frequency. No one can construct an amplifier which amplifies signals over a wide range. So every transmitting frequency has to be changed to one particular frequency. This is known as INTERMEDIATE frequency (IF) This is quite possible by getting beats. So a signal is to generated whose frequency is just more than the incoming frequency by IF This signal is named as local singnal which is generated by the LOCAL oscillator.
The product of the period and the frequency of a harmonic oscillator is always equal to?

What is the usage of frequency?
It is a device or electronic circuit that changes the frequency of an oscillator according to the amplitude of modulating signal. For instance, if the modulation is linear, the modulator changes the frequency proportional to the amplitude of the modulating voltage.
What are the advantages of wien bridge oscillator?
RC phase shift oscillator is used to generate frequency in audio range and it is a fixed audio frequency oscillator where as wien bridge oscillator is a variable audio frequency oscillator for high frequency oscillations it is better to design wide band amplifier with LC network
Why oscillator is needed in transmitter circuit?
Low frequency signal are not able to get propagated throught longer distance. So it is to be carried by a carrier wave. Hence high frequency carrier wave is to be generated by the help of an oscillator. So we need an oscillator here a crystal oscillator to produce high frequency carrier waves.
Which oscillator produces 1MHz frequency?
crystal oscillator
Why transistor is used?
for high frequency applications(RF oscillator) we use BF 194
What is a frequency range of LC oscillator?
depends on the oscillator and its purpose

5MHz
Applications of wien bridge oscillator?
A Wein Bridge Oscillator is a oscillator which is used for the measurement of Audio Frequency.
What are the advantages of clap oscillator?
clapp oscillator have frequency more stable and accurate than colpitts oscillator.
How are FM signal generated?
There are several methods for generating FM signals but they all basically involve an oscillator with an electrically adjustable frequency. This type of oscillator uses an input voltage to affect the frequency of its output. For example, when the applied voltage increases, the oscillator output frequency increases and when the applied voltage decreases, the oscillator output frequency decreases as well. If no voltage is applied to the oscillator its output will be a signal at its centre frequency. The amount of frequency variations is deviated around the oscillators' centre frequency.
What is the difference between crystal and local oscillator?
oscillator frequency is different.crystal working piezo electric effect
What is a local oscillation?
A local oscillator is used in a superheterodyne radio circuit for example.The incoming radio frequency is mixed with an internal local oscillator circuit to generate a new intermediate frequency (IF) .The local oscillator usually runs at a frequency of 470kHz and is generated by an inductor and capacitor(LC oscillator)
