Frequency Response of second order Active Filters 
Consider the following specifications and calculate the high cut-off frequency for the circuit given.
How can a first order lowpass filter can be converted into second order low pass filter
Find the gain and phase angle of the 2nd order low pass filter where, passband gain of the filter is 5.Frequency and high cut-off frequency of the filter are 3000Hz and 1KHz.
The pass band voltage gain of a second order low pass butter worth filter is
Frequency scaling is done using
A second order low pass filter is given an input frequency of 30KHz and produce an output having phase angle of 79 degree.Determine the pass band gain of the filter.
