All the High Pass 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 High Pass Filter. In an ancient era, there were conditions where users communicate via telephones over long distances. During this conversation users used to talk slowly and in a higher pitch so that the audio message is delivered to the receiver clearly. To overcome this drawback an electronic device filter was designed. A filter is a device that avoids unwanted signals and allows the required signals. They are classified based on the frequencies of high pass filter and low pass filter. A filter that allows higher frequency type signals and averts lower frequency type signals in an HPF (High Pass Filter). They are constructed using passive components resistor and capacitor. Where the resistor is placed in parallel to the input and the capacitor is placed in series. They are classified into 7 types namely RC filter, RL filter, Inverted L, T filter, n filter, Op-amp filter, and Butterworth filter. The advantages of HPF include allowing frequency above the cut-off, preserving high frequency, and image sharping. The applications of HPF include speakers, noise minimization, and image processing. 1). A High Pass filter is a ___ filter? Electric Electronic Mechanical Both a and b None Hint 2).
