Which frequency? Frequency in Hertz can be accepted as linear frequency. What is non linear is usually the method of "presenting" it, like a non linear logarithmic scale.
Also there is the matter of angular frequency defined as w = 2*π*f, where f is linear frequency (Hz or s^-1).
What else can I help you with?
Is resistance a linear device?
YES it is linear. It is a passive device classified as linear however as frequency increases its behavior will change.
Which of the following modulation is non linear?
frequency modulation is non linear due to cross over term.
How do you define angular frequency?
Angular frequency is related to linear frequency as w = 2 x pi x f wher w = angular frequency linear frequency is cycles per second, or number of oscillations per second, called Hertz angular frequency for f = 1 = 2 pi f = 2 pi, or one revolution. It has units of radians per second
Why the linear combination of a low frequency intelligence signal and a high frequency carrier signal is not effective as a radio transmission?
to shift the frequency of information signal ,at the frequency domain to a higher frequency ...so the information can be transmitted to the receiver.
How does the amplitude change as the frequency increases?
As the frequency increases, the amplitude of a wave remains constant if the system is linear. In non-linear systems, the amplitude may change as the frequency increases due to factors such as resonance or saturation effects.
What is the importance of frequency transformation in filter design?
Importance of frequency transformation in filter design are the steerable filters, synthesized as a linear combination of a set of basis filters. The frequency transformation technique is a classical.
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.
Would the linear combination of a low frequency intelligence signal and a high frequency carrier signal be effective as a radio transmission?
Yes, a linear combination of a low-frequency intelligence signal and a high-frequency carrier signal can be effective for radio transmission. This method, known as amplitude modulation (AM) or frequency modulation (FM), allows the low-frequency signal to be transmitted over longer distances by utilizing the high-frequency carrier wave. The carrier wave effectively "carries" the information, enabling it to be received and demodulated by appropriate receivers. This technique is fundamental in broadcasting and communication systems.
Is the plot of current versus frequency symmetrical about the resonant frequency in LRC circuit?
The plot of current vs. frequency is not symmetric because the equations for inductive reactance and capacitive reactance are not symmetric. One is linear and the other is inverse.
What is the relation between the spring constant and the frequency?
angular frequency = square root (K/m) wher k is spring constant and m = mass linear frequency = 1/2pi times square root (K/m)
What is the difference between linear and non linear optics?
In the case of linear optical transitions, an electron absorbs a photon from the incoming light and makes a transition to the next higher unoccupied allowed state. When this electron relaxes it emits a photon of frequency less than or equal to the frequency of the incident light (Figure 1.3a). SHG on the other hand is a two-photon process where this excited electron absorbs another photon of same frequency and makes a transition to reach another allowed state at higher energy. This electron when falling back to its original 39 state emits a photon of a frequency which is two times that of the incident light (Figure 1.3b). This results in the frequency doubling in the output.
What is the difference between linear and nonlinear problems and how do you?
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.
