  • Essay / Bandpass Filter

    Table of ContentsExperiment SummaryTopics for DiscussionTime RequiredThis laboratory experiment is carried out to find out the center frequency of the bandpass filter. The center frequency was found using a circuit diagram and the data table formed from the observations. In this laboratory experiment, a stack of low and high band pass filters were also prepared. During the experiment, a pair of polarized capacitors was used. This pair of polarized capacitors with resistors was used to control the cutoff frequency. These capacitors have been added in a particular way to increase their capacitance because the capacitance of the capacitors depends on how they are connected. In this experiment, the band-pass filter is trained using low-pass filters and high-pass filters connected to each other, so that the band-pass filter can collectively pass the signals which have both low and high frequency ranges. to plagiarism.

The band of different frequencies can have any width, and this width is called the filter bandwidth. The cascade process can form the bandpass filter. As part of this process, cascading of high-pass and low-pass filters is performed. Cascading low-pass and high-pass filters means using the output of the first filter as the input of the second filter. The bandpass filter can be used to isolate frequencies that fall within a particular band or group of frequencies. Each section of the filter resembles the frequencies of the previous filter. The high pass and low pass filters have their resistors and capacitors interchanged to form the band pass filter. The different applications in which the bandpass filter is used have filter bands and frequencies of a wider range composed of mixed signals. The circuit used to filter frequencies is designed by combining the properties of low and high bandpass filters. This bandpass filter is designed to transmit signals in frequency bands. Bandwidth can also be defined as the frequency ranges that exist at any point between the cutoff frequencies of the low-pass and high-pass filters or the frequency band. Cutoff frequency 1, or we can say CF1, is the frequency below which the transfer function of the signals has the maximum value equivalent to l/v2. Cutoff frequency 2 is the highest frequency at which the signal transfer function has maximum values ​​equivalent to l/v2. The center frequency is the frequency at which the transfer of the signal function is maximum. The above circuit diagram denotes a 741 op-amp circuit. This circuit has two resistors and two capacitors. R1 = 2.2kO, R2 = 22kO, C1 = 10nF, C2 = 4.7nF Center frequency H In the equation above: fr represents the center frequency. fL represents the lower cutoff frequency point. fH represents the highest cutoff frequency point. Using the above circuit information, we found the cutoff frequencies of the low pass and high pass filters in this lab report. The input voltage of the circuit calculated by applying the sine waves is used to estimate the output voltage of the circuit. In this lab report, we calculated and compared the cutoff frequency of low-pass and high-pass filters. We also calculated the frequency..
