You must have a feedback loop, the loop gain must be equal to unity (1), and there must be 0 or integer multiple of 360 degrees.
Large population oscillations refer to significant and repeated fluctuations in the size of a population over a certain period of time. This can be influenced by various factors such as availability of resources, predation, disease, or environmental conditions. Understanding these oscillations can provide insights into the dynamics and stability of populations.
oscillations in which the amplitude increases over time.
Nonlinear Oscillations - journal - was created in 1998.
To start the oscillation with the constant amplitude, positive feedback is not the only sufficient condition. Oscillator circuit must satisfy the following two conditions known as Barkhausen conditions:1. The first condition is that the magnitude of the loop gain (Aβ) must be unity. This means the product of gain of amplifier 'A' and the gain of feedback network 'β' has to be unity.2. The second condition is that the phase shift around the loop must be 360° or 0°. This means, the phase shift through the amplifier and feedback network has to be 360° or 0°.In practice, to obtain the sustained oscillations at desired frequency of oscillations, oscillator circuit must satisfy some of the basic requirements such as,Circuit must have positive feedbackWhen positive feedback is used in the circuit, the overall circuit gain is given by,

no , 1hz is 1 oscillation , 1000hz ( 1khz ) is 1000 oscillations !
The Barkhausen criterion is a principle used to determine the conditions required for oscillations in a circuit. It states that for sustained oscillations to occur, the total phase shift around a feedback loop must be an integral multiple of 360 degrees and the loop gain must be equal to or greater than unity.
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.
In a torsion pendulum, torsional oscillations are observed. These oscillations involve the twisting of a wire or shaft that suspends the pendulum mass, resulting in a rotational motion back and forth. The restoring force for these oscillations comes from the torsional stiffness of the wire or shaft.
