This that have both low and high-frequency

This labexperiment was carried out with the purpose of finding out the centralfrequency of the band pass filter. Thecentral frequency was found with the help of circuit diagram and from the datatable formed from the observations. In this lab experiment, a stack oflow and high band pass filters were alsoprepared.During the experiment a couple ofpolarized capacitors were used, thesepair of polarized capacitors along with resistors was used to control the cutoff frequency. Thesecapacitors were then added in a particular way to increase their capacity due tothe fact that the capacity of thecapacitors is governed by the way they are linked. Inthis experiment, the bandpass filter is formed with the helpof low pass filters and high pass filters that were connected opposite toeach other so that the bandpassfilter could pass the signals that have both low and high-frequency ranges collectively. A band pass filter could pass thesignals with certain band or recurrence without contorting any of theinformation or without delivering any clamor. Thecascading process can form the bandpass filter.

Under this process,cascading of high and low pass filter is performed. Cascading of low andhigh pass filter means using the output of the first filter as the input of the second filter.The bandpass filtercan be utilized to segregate the frequencies that exist in an assigned band orgroup of frequencies.Every section of the filter looks likethe frequencies of the formerfilter. The high and low pass filters have their resistors andcapacitors that interchange to form the bandpassfilter. Thevarious applications in which bandpass filter is used havefilter’ bands and frequencies of a much broader fabricated fromcombined signals.The circuit that is used in filtering the frequencies isdesigned by combining the properties ofthe low and high bandpass filters.

Thisbandpass filter is designed to skip theindicators within the bands of frequencies.Bandwidth can also be defined as the frequencyranges that exist on any point betweencut off frequencies of the low and high pass filter or the band of frequencies. Thecutoff frequency 1, or we can say CF1, isthe lower frequency at which the transfer function of signals has the maximum valueequivalent to l/?2.The cutofffrequency 2 is the higher frequency at which the transfer function of signals has the maximum values equivalent to l/?2. Thecenter frequency is the frequency at which transferring of the signal functionis at maximum.
