What is an Unstable oscillator?
An unstable oscillator is an oscillator that cannot hold one or more of its parameters constant (e.g. the frequency drifts, the amplitude drifts).
What is the modulation 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.
A sinusoidal force with a given amplitude is applied to an oscillator At resonance the amplitude of the oscillation is limited by?
no limit
How are frequency and amplitude related?
They're not. The same amplitude can have high or low frequency, and the same frequency can have large or small amplitude.
What is the difference between crystal and local oscillator?
oscillator frequency is different.crystal working piezo electric effect

What is an Unstable oscillator?
An unstable oscillator is an oscillator that cannot hold one or more of its parameters constant (e.g. the frequency drifts, the amplitude drifts).
Does frequency depend on amplitude for harmonic oscillators?
No, the frequency of a harmonic oscillator does not depend on its amplitude. The frequency is determined by the properties of the system, such as mass and spring constant, and remains constant regardless of the amplitude of the oscillation.
What is the usage of frequency modulation?
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 is amplifier and oscillator?
amplifier is electronic circuit which is used to increase the amplitude of the input signal without affecting its frequency and phase.
What is the formula for the maximum acceleration of a simple harmonic oscillator?
The maximum acceleration of a simple harmonic oscillator can be calculated using the formula a_max = ω^2 * A, where ω is the angular frequency and A is the amplitude of the oscillation.
What is the modulation 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 is the amplitude when you are given the mass and period and position of the oscillator and the velocity of the oscillator?
amplitude is the maximum displacement right from the equilibrium position. It does not depend on the mass, period or velocity. Recall displacement at any instant t is y = A sin 2 pi f t or A sin 2 pi t/T f = frequency and T - time period.
Operation of a transformer?
Transforming a signal without changing its frequency.(amplitude can be changed)
What is a gradual loss of amplitude of an oscillator called?
This is known as damping. Damping refers to the gradual decrease in the amplitude of an oscillator's motion due to the energy dissipation in the system.
Factors that affect frequency stability and amplitude stability of oscillator?
Practically, there are some factors that affect the frequency stability of Variation in temperature Oscillator • Circuit Components - Values of R, L and C changes with temperature • Transistor Parameters - causes variation in transistor parameters • Supply Voltages - Variations in power supply • Stray Capacitances • Output Load - Variations of load causes a change in effective resistance • Inter‐element Capacitance
What is a frequency range of LC oscillator?
depends on the oscillator and its purpose
