High pass filters are used in circuits such as microphones to block out DC signals and pass the AC. In a microphone, DC power is used to power the microphone but should not appear on the output with the audio signal. Only the AC should appear on output which represents the voice signal, music, etc. To block out DC and pass AC, a high pass filter is used.

What are the different types of filter(electronic)?
You can have low-pass, band pass or high-pass filters. You can also have all-pass filters designed to provide a time-delay. Then you can have active or passive filters. Filters can be designed to give different types of reponse, the main ones being Butterworth, Chebyshev and Elliptical, with Bessel used for time-delay.
Canny edge filters acts as a low pass or high pass?
low pass
Why do we go for low pass filters?
Low pass filters are used for various purposes in different areas.
What type of filter is most likely to be suitable for eliminating mains hum?
High-pass filters
Types of air filters used in microbiology?
High Efficiency Particulate Air (HEPA) filters are used in microbiological containment protocols.
What are the applications of Butterworth filters?
especially it is very much useful in high quality AUDIO applications because of its flat response in both pass band and stop band where as chebyshev will be useful in signal monitoring applications where the phase is not important criterialow pass filters are used to filter noise from a circuit .noise is a high freequncy signal, when passed through a low pass filter most of the noise is removed and aclear sound is produced
What is a filter capacitor?
Capacitor has many applications in electronics circuits, one of its application is in FILTERS. Mainly two types of Filters are formed with the help of capacitor namely, i)Low Pass Filter(LPF) ii)High Pass Filter(HPF) Impedance of capacitor is inversely propotional to the frequency, therefore a capacitor in series with resistor will act as Low Pass Filter. since all the high frequency are passed to ground.
What do the letters HEPA stand for in filters?
HEPA filters are High-Efficiency Particle Arresting filters.

SAnd is used in sand filters. rocks are not used in pool filters.

Why does the blood pass through the liver?
The liver filters the blood.
Why water filters are used?
water filters are used to filter water
