Why inductor use in series capacitor in parallel?
That depends on the type of circuit you are talking about. Sometimes both an inductor and capacitor are both in parallel with each other. This is called a tank circuit. Sometimes they are both used in series. These are both examples of resonant circuits. Sometimes the inductor can be in parallel with an applied voltage and the capacitor in series. This is a form of high pass filter. On the other hand, the inductor can be in series and the capacitor in parallel to for a low pass filter.
Q factor of low pass filter?
The Q factor is describing how sharp the dropoff of the filter is relative to the pass band. Wikipedia has a decent writeup on Q factor. The more components you use to make the filter, and the lower the cutoff frequency, the higher the Q will be.
What will happen if you pass ac current passes through a inductor?
magnetic flux will be induced its use to rotate the shaft or given some force
Why we use band pass filter in binary phase shift keying receiver or not low pass filter?
The bpsk receiver requires a particular band of frequencies to be passed to generate the required carrier which is further divided and then given to the demodulator. So the basic use of the bpf is to bandlimit the signal generated by the square law device and attenuate any dc levels otherwise. Lpf would simply allow all low frequencies to pass, which is not desired.
What is asynchronous and self synchronous demodulation?
Synchronous demodulation is done using the same modulating signals such as cos(2000t) that was used in the transmitter. It still has to use Band-Pass (if multiple signals are present) and Low-Pass filter

How do you use series RLC circuit as band pass filter?
by combining a low-pass filter with a high-pass filter.[1]
What is the use cro in rlc circuit?
The use of a Capacitor-Resistor (CR) or Resistor-Inductor (RL) in an RLC circuit helps determine the frequency response and filter characteristics of the circuit. The CR combination provides high-pass filter characteristics, allowing higher frequencies to pass through, while the RL combination provides low-pass filter characteristics, allowing lower frequencies to pass through. These components are commonly used in audio crossovers and signal processing applications to control frequency ranges.
How can you filter harmonics from a square wave?
You can use a low-pass filter (passive is mostly coils) but you won't end up with a square wave.
How do you use a synthesizer?
To begin with there is a source of sound which is an oscillator which can have many different wave forms which include saw, square, triangle and sine. Then there is the filter section, there are 3 different types of filter which are high pass, low pass and band pass, the most common of which is the low pass. Which according to the amount will filter out the low parts of the frequency. Band and high pass do the same except they filter out the high and a specified band. Low frequency oscillators have the ability to modulate pitch, filter frequency and others. You than press a key and according to the setting explained above a certain noise comes out.
Will loading effect occur in cascading of LR low pass and LR high pass filter?
Yes, you have to use an op-amp buffer to prevent the loading effect.
Q factor of low pass filter?
The Q factor is describing how sharp the dropoff of the filter is relative to the pass band. Wikipedia has a decent writeup on Q factor. The more components you use to make the filter, and the lower the cutoff frequency, the higher the Q will be.

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.

Why you use inductor?
we use the inductor because it helps the circuit to have an appropriate amount of current, so that the circuit in the appliance will say longer.
