it uses positve feed back
A positive
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.
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.
The feed back factor in the oscillator refers to the output which is usually sinusoidal.
There are many different types of oscillator circuits, the majority of which use positive feedback.
If it's a pregnancy test the answer is no, A test can come back negative even though its positive. But if it's positive, it's positive 99% of the time.
In Amplifier if feedback is occures when the feedback signals is in phase with the input signal the feedback is known as Positive feedback. And the feedback is occures when the feedback signals is out of phase with the input signal the feedback is known as negative feedback.
It depends on the context. It may mean quiet, unruffled (positive) or it could mean too laid back to do anything (negative).
Connect the Positive + battery cable to the positive + battery post first. Then connect the Negative - cable to the negative - battery post.
oscillator is an electronic device used to generate wave form by using the concept of feed back.
