A band pass filter is one which Correct Answer Passes frequencies between two designated cut off frequencies

The name of the filter is decided by the type of frequency it passes:

Low pass filter:

This filter passes the low frequency and blocks or attenuates the high frequency.

It has only one cut off frequency above which it starts to attenuate the signals.

Band Stop Filter:

This filter blocks a certain band of frequencies and passes low and high frequencies.

It has two corner frequencies, smaller (fc1) and larger (fc2).

It attenuates signals that fall in between these two corner frequencies.

Note: Narrow bandstop filter is called a notch filter.

The low pass, high pass, band pass and band stop filters can be designed by applying a specific transformation to a normalized low pass filter.
A rotary drum filter with 30% submergence is used to filter concentrated aqueous slurry of calcium carbonate containing 15lb of solids per cubic foot of water. The pressure–drop is 2011Hg. If the filter cake contains 50% mixture (wet basis), calculate the filter area required to filter 10 gal/min of slurry. The filter cycle time is 5 min. The specific cake resistance depends on the pressure–drop as: α (ft/lb) = α (Δp)0.26, where α = 2.90×1010 Viscosity of the filtrate = 6.72×10-4 lb/ft-s. Density of calcium carbonate = 168.8 lb/ft3. Neglect filter medium resistance.
