What is the difference between band pass filter and band reject filter?

Band-Pass and Band-Reject A band-pass filter, in contrast, passes frequencies that fall only within a relatively narrow range, and a band-reject filter (also called a band-stop or notch filter) passes all frequencies except those that fall within a relatively narrow range.

Which filter has best stop band response?

Which among the following has the best stop band response? Explanation: The cauer filter has a ripple pass band and a ripple stop band. So, generally cauer filter gives the best stop band response among the three.

What is a band reject filter used for?

Background: A Band Stop Filter, also sometimes called a notch or band reject filter allows a specific range of frequencies to not pass to the output, while allowing lower and higher frequencies to pass with little attenuation.

What are the most commonly used active filters *?

7. What are the most commonly used active filters? Explanation: All the mentioned filters use op-amp as active element and capacitors & resistors as passive elements. 8.

What are the advantages of active filters over passive filters?

Active filters have some definite advantages over passive versions, including the ability to provide signal gain, higher input and lower output impedances, no need for buffer amplifiers, and less dependency on inductors, which add expense. Most electronic filters are linear.

How many types of band reject filters are present?

Explanation: Band-reject filters are also called as band elimination filters. They are classified into two types. ii) Narrow band-reject filter.

Which LP filter is the best having the slope of stop band?

Elliptic Filter: This filter has the sharpest roll-off of all filters in the transition region but has ripples in both the pass band and stop band regions.

How many types of band-reject filters are present?

What are the disadvantages of active filters over passive filters?

Disadvantages of active filters:

• It is expensive.
• It provides a complex control system.
• The active filter is only suitable for low or moderate frequencies.
• It can not handle a large amount of power.
• It requires DC power supply for their operation.
• This filter is limited in their frequency range.
