There are three conditions. These include positive feedback, the phase near the circuit needs to be either 36 or zero degrees, and the loop gain should be equal or greater than 1.

∙ 13y agoA: Oscillation will occurs if there is positive feedback and/or phase feedback.
2nd Answer:
According to my old electronics textbooks, you need a circuit, a frequency-determining device or system, and amplification. The "circuit" can be either an electronic circuit, or part electronic and part acoustic.

Mass and pendulum oscillation?
Mass oscillation time period = 2 pi sq rt. (m/k) Pendulum oscillation time period = 2 pi sq rt. (l/g)
What is the wave height of wave of oscillation?
maximum and or minimum peak of any signal measured on an oscilloscope
What is oscillation of a spring?
The oscillation of a spring is the motion that the spring makes when disturbed. Imagine holding the end of a spring and hanging a weight to the other end. If you do not disturb the weight, it will stay in a static position. However, when you pull down on the weight and let go, the spring "oscillates" up and down. The spring could also be compressed and released, creating the same effect. The up and down motion, which has a specific velocity and period relating to the spring constant k, is oscillation.
Do alkali metals have metallic luster?
All Alkali metals show metallic lustre ,which can be explained by the oscillation of free electrons.
What happens if you put a inductor in parallel with a capacitor?
both of these components connected in parallel will cause an oscillation of energy, meaning the capacitor will charge and then discharge through the inductor , which will then build up a magnetic field and discharge through the cap again , and this oscillation will go on for quite some time and then finally die out , and also if a multimeter is place across the cap it should short out , because it's as if you have connected a piece of wire right across it ...
Is walking a in-phase oscillation or out of phase oscillation?
out
When was Oscillation Isolator created?
Oscillation Isolator was created in 2009.
Is oscillation a wave?
NO,oscillation is not necessarily a wave because energy is not transported in oscillation.In oscillation there is no space periodicity.An oscillation is periodic in time only where as a wave is periodic in time and space both.
How can you use oscillation in a sentence?
Please put oscillation in a complete sentence.
What is a sentence using the word oscillation?
The object has an oscillation frequency of 23 hz.
What is a subsequent oscillation?
It is an oscillation that occurs constantly or in order with respect to the perod of oscillations
What is light an oscillation of?
Light is an electromagnetic wave, that is, an oscillation of both the electric and the magnetic fields.
Is oscillation not a factor in sound generation of a synthesizer?
Oscillation IS a factor in sound generation of a synthesizer.
How does surface area affect damping of an oscillation?
The larger the surface area, the larger the damping of an oscillation
What is torsional oscillation?
Torsion = turning Oscillation = repeated motion toraion oscillation is repeated turing back and forth. Imagine you have a weight hanging on the end of a piece of string. Twist the weight and, when released, it will oscillate torsionally.
What is oscillation in art?
music
What is the difference between underdamped and overdamped oscillations?
Damped (or free) oscillation occurs when an object is set to vibrate at its natural frequency while forced oscillation involves the application of a force to keep an object in constant or repetitive motion.
