What is the frequency of ripple component in the output inductor filter?

It depends on the rectifier.
For a half-wave, it's the same as the AC mains: i.e. 60 Hz mains gives 60 Hz ripple.
For a full-wave or a bridge, it's twice the AC mains: 60 Hz mains gives 120 Hz ripple.
Three-phase systems are more complicated, so you would need to check in an electrical engineering book.

Which filter is practically preferred to get pure DC output?
pi filter is best using inductor and capacitor.
Why there are null frequency in MTI filter output?
because.... there isn't
Why there are only RC filters and not RLC filters used with IC.why inductor is not used?
The inductor is a component which produces inductance. This inductance which opposes any change of current through it, so if any changes occurred in an IC the output will be changed. so inductor is not used.
Could anybody please explain how exactly high pass and low pass filters work?
Filters are composed of capacitors and inductors. These component "react" differently to different frequencies. If you modulated the voltage frequency to a series capacitor, it would start out looking like a very big resistance, which would become incrementally smaller as the frequency is increased. Inductors act in the exact opposite fashion. A simple lowpass filter is compossed of a resistance and capacitor in series, with the output across the capacitor. Using a voltage divider: Voutput = Vinput * (resistance of cap) / (resistance of cap + R) A simple highpass filter is composed the same, with the output across the resistor. This type of filter is a first order filter, because there is one inductor or capacitor. Adding more of these elements will cause rippling in the frequency response, and can cause the rolloff / decay to occur faster. Putting two capacitors in series or parallel "looks" like one element, so for a second order filter you must use a cap and an inductor. For a third order, you must use two of one and one of the other "in between" them - for example have the input to a capacitor, where the other side is tied to the inductor and other capacitor; the inductor's other terminal is connected to ground, and the output is from the other capacitors second terminal.
What is the difference between with capacitor rectifier and without capacitor rectifier?
To know the difference between capacitor and non capacitor rectifiers one must study what is the function of filter part.the filter part consists of capacitors or inductors or combination of both. the output of a simple diode rectifier is pulsating dc which means it consists of both dc part and ac part. filters are used to remove the ac part from such an output. capacitor filter means that a capacitor is used for filtering out the ac part. non capacitor or inductor filter means that an inductor is used for filtering out the ac part. There is another type called pii filter where both inductor and capacitor are used. Pii filter is the best kind of filter available

Which is defined as the time delay that a signal component of frequency f undergoes as it passes from the input to output of the system?
Phase delay
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.
Electronic component used to control speed of a motor?
In industrial, there is a device called variable frequency drive (allso frequency inverter, ac drive) to control the motor speed by adjusting output frequency.
What is the difference between an inductive low pass filter and a capacitive low pass filter?
Where you are measuring. A simple filter will be two elements - a capacitor or inductor and a resistor. A capacitor will tend to "trap" low frequencies. In the case of a lowpass filter made of a capacitor and resistor, the output voltage will be measured across the capacitor. Inductors are the opposite, so the output would be across the resistor.
Difference between m-derived filters and constant k-filters?
in m derived impedance matching is possible but not in case of constant k filters. compared to constant k filter m derived filter has a sharp cutoff frequency. in k type the attenuation is not complete in the stop band.where as in the m derived just beyond the attenuation rises to max just after the cut off frequency. in m derived a capacitor and a inductor are taken in series at the output.
Why an inductor filter cannot be used in half wave rectifier?
I am not exactly sure why it is said it can't be used, I myslef was searching for an answer when I came across this, I have a general idea about this, why I would like to share. There can be two possible reasons. 1. The inductor produces a back-emf which opposes any change in current, but in the output of a HWR, the decrease in current and a no current state predominates a increase in current, so the inductor will naturally oppose a increase in current, which will mean a low dc voltage is obtained. [i.e. lower than the peak value] 2. The reactance of inductor increases with increase in frequency, the output frequency of a HWR is half that of a FWR. Thus filtering of higher harmonic waves is favoured.
