in general no. however some types of oscillators have enable or frequency selectinputs, without which they won't operate.

What type of feedback used in the oscillator circuit?

There are many different types of oscillator circuits, the majority of which use positive feedback.


Does an oscillator have input?

Yes, an oscillator typically requires an input signal to generate its output waveform. The input signal could be a voltage or current signal that initiates and drives the oscillation process within the oscillator circuit.


How can an amplifier become an oscillator?

An amplifier can become and oscillator by adding positive feedback from the output back to the input. Positive feedback means that the phase of the signal fed back to the input is the same as the phase of the output signal. In the case of a high frequency oscillator, a tuned circuit (inductor and capacitor) or a quartz crystal in the input circuit will determine the frequency of oscillation.


Difference between oscillator and amplifier?

The amplifier projects the audio signal into something we can comprehend. The oscillator creates a fixed or variable pitch, which is fed to the amplifier. Amplifiers are circuits which transfer an input signal into an output signal. Oscillators are autonomous circuits powered by a constant energy source. They produce a steady state signal e.g. a sinusoidal signal or a chaotic signal.


How does an oscillator work?

An oscillator works in different ways in different electronic equipment. For example, there is a quartz oscillator in a quartz watch that can keep track of the time. A pendulum of a clock is an oscillator that goes back and forth using potential and kinetic energy.


Why a occilator requires positive feedback?

An oscillator requires positive feedback to sustain oscillations by reinforcing the input signal and producing an output that is in-phase with the input. Positive feedback increases the overall gain of the system, allowing the circuit to overcome losses and maintain sustained oscillations without external stimuli.


What is a generic function?

Function generator can better be called as signal generator.It produces different types of signal like sine, saw tooth, triangular, pulse wave forms etc... can be produced.For testing any circuits which input must be a wave form like oscillator circuits function generator is used.


What is a positive and negative feedback?

Negative feed back, is where some of the output is fed back to the input, in reverse phase. This limits the output, to protect the circuit and improve stability and fidelity.Positive feedback is when some of the output signal is fed back to the input in phase. This generally causes the circuit to run away into oscillation. The popular use is to turn a simple amplifier into an oscillator, for use in radio circuits and timing.It is also an unpleasant symptom of a badly set up Public address system, when the microphone hears the output from the speakers, which is then reinforced and you get unwanted oscillation, known as 'Howl round'.


What is the difference between oscillator and multivibrators?

Oscillator is an electronic circuit which can generate oscillating sin signal without any oscillating input with use of positive feedback Multivibrator is a two stage RC coupled amplifier circuit which can generate squae signal without ac input


Why you go for wien bridge oscillator?

It generates an oscillatory output signal without having any input source


Why is positive feedback used in oscillators?

Positive feedback is used in oscillators to keep them running or oscillating. An oscillator is basically an amplifier which has a feedback path from the output back to the input. This permits a portion of the output signal to get back to the input to "keep things going" in stage - to keep things oscillating. The feedback must be positive so that it will "contribute" to the stage being able to keep oscillating. If the feedback was negative, it would serve to damp the oscillation and to "kill" the oscillator.


How a triode valve can be used as an oscillator?

An amplifier can be made into an oscillator by feeding back part of the output to the input. A simple oscillator uses a Frequency Determining Network (FDN) in the feedback path to give a predictable frequency of oscillation. There are some simple requirements - the valve must be capable of operating at the desired frequency, and the total gain (loop gain) from output to input must be at least unity. Many oscillators use tuned inductive-capacitive circuits, but it's also possible to use a resistive-capacitive circuit, or a quartz crystal as the FDN.
