Notch Filter/Band Reject Filter Question & Answers

May 2, 2022 By WatElectronics

This article lists 50 Notch Filter/Band Reject Filter MCQs for engineering students. All the Notch Filter/Band Reject Filter Questions & Answers given below include a hint and a link wherever possible to the relevant topic. This is helpful for users who are preparing for their exams, interviews, or professionals who would like to brush up on their fundamentals on Notch Filter/Band Reject Filter.

Bandstop/Band Reject filter or band elimination filter operates opposite to Bandpass filter. The purpose of this type of filter is to reduce the distortion in the signal.

This filter blocks specific frequencies ranging between FH and FL cut-off frequencies. But bypass the frequencies which are above the FH and FL frequencies.

Band Elimination/Band rejection Filter using an RLC circuit is designed to connect these components in parallel or series configuration. The output is drawn across the Inductor(L) and Capacitor(C) components connected in series.

This circuit can be operated in short and open circuits based on the applied frequencies. For instance, the BRF circuit is short-circuited when capacitors are short-circuited and inductors are open and for open-circuited BRF it's vice versa.

A Notch filter is a twin T network due to the existence of dual T-shaped-based networks. Applications of the band-stop filter include Image and signal processing.
