File Name: viva questions on low pass and high pass filter .zip
A high pass filter will allow the frequencies which are higher than the cut-off frequency and attenuate the frequencies lower than the cut off frequency.
If we talk about high pass filter, so it is a circuit which allows the high frequency to pass through it while it will block low frequencies.
Solved examples with detailed answer description, explanation are given and it would be easy to understand. Here you can find objective type Electrical Engineering Passive Filters questions and answers for interview and entrance examination. Multiple choice and true or false type questions are also provided. You can easily solve all kind of Electrical Engineering questions based on Passive Filters by practicing the objective type exercises given below, also get shortcut methods to solve Electrical Engineering Passive Filters problems. In a certain parallel resonant band-pass filter, the resonant frequency is 14 kHz.
There was an era where while making a telephone call over distance places, one had to put his mouth very close to the transmitter, speak very slowly and very loudly so that message can be heard clearly by the person at the other end. Today, we can even make video calls over worldwide with high-quality resolutions. The secret of such a tremendous development of technology lies in Electrical filter theory and Transmission line theory. Electrical filters are circuits that pass only selected band of frequencies while attenuating other unwanted frequencies. One of such filters is High pass filter. The value of cutoff frequency depends on the design of the filter. The basic High Pass Filter is built by a series connection of capacitor and resistor.

Explain what is a dc power supply? The part of the equipment that converts ac into dc is called dc power supply. Explain what is a rectifier? A rectifier is a device which converts alternating current or voltage into unidirectional current or voltage. Explain what is PIV of a diode in a rectifier circuit?
A filter is often used in electronic circuits to block or allow a select frequency to the circuit. For example, if the circuit in question works on DC power, we could use a low pass filter LPF and only allow low frequencies to pass through. The filter is designed around a cut off frequency, and only allows the low frequencies to pass through. Now, while designing we can set the cut off frequency as required. The same can be done for high pass, band pass and band stop filters.

In such circuit, the output is taken across the resistor and practically reactance of the capacitor decrease with increasing frequency.
