Major objective of this case study is to Experiment on Design of Active Filters. Here experiment Design of Active Filters theoretically. The objective associated with the experiment will be to investigate the functions of some other type of filter namely Low pass filters, High pass filters. Main filters and Butterworth filters can be investigated. To complete this experiment, here need some Equipment’s like, Power supply, Signal generator, Resistors, Capacitors, Oscilloscope and Operational Amplifiers.
