Phase delay
A linear circuit is an electric circuit in which, for a sinusoidal input voltage of frequency f, any output of the circuit (current through any component, voltage across any component, etc.) is also sinusoidal with frequency f. Note that the output need not be in phase with the input.
In industrial, there is a device called variable frequency drive (allso frequency inverter, ac drive) to control the motor speed by adjusting output frequency.
The output signal-to-noise ratio is defined as the ratio of the average output signal power to the average output noise power. From Equation (2.140), we see that the message component in the discriminator output, and therefore the low-pass filter output, is
twice the input frequency
Audio output frequency is that range of frequencies that can be heard. For humans, that is generally considered to be the range of 20Hz to 20kHz.
In natural frequencies the output of the system will be less than the maximum level. In the resonance frequency the output of the system will be the maximum level.
Ripple factor (γ) may be defined as the ratio of the root mean square (rms) valueof the ripple voltage to the absolute value of the dc component of the output ...
answer for me please
There are several methods for generating FM signals but they all basically involve an oscillator with an electrically adjustable frequency. This type of oscillator uses an input voltage to affect the frequency of its output. For example, when the applied voltage increases, the oscillator output frequency increases and when the applied voltage decreases, the oscillator output frequency decreases as well. If no voltage is applied to the oscillator its output will be a signal at its centre frequency. The amount of frequency variations is deviated around the oscillators' centre frequency.

The difference is in the output frequency.
Frequency response is the measure of the frequency of the output a device gives in response to a stimulus that it receives. The frequency response is a characteristic of the device.
