I implemented a BandPass Filter of 2nd Order into simulink by using Analog components : Resistors , Capacitors and Op.
To achieve this goal, I started by implementing the LowPass and HighPass filters separately and ended up by adding an amplifier to amplify (increase) the amplitude of the signal.
Circuit of BandPass :
BandPass Filter Model into simulink :
So, by Cascading the HighPass and LowPass filters together I obtain a BandPass Filter.
The range of BandPass filter = [fc1 , fc2].
fc1 : Cutoff frequency of HighPass filter.
fc2 : Cutoff frequency of LowPass filter.
fc1 = 1/(2piR1C1)
fc2 = 1/(2piR2C2)
In this example I have chosen fc1 = 16Khz and fc2 = 24 Khz.
By fixing the values of the R1 and R2 you can find the values C1 and C2.
Amplification := 1+(R4/R3)
