Answer #1

Answer :- 1) The second order active filter can be designed as shown below-

Let us assume, R1 = 1 kohm then for gain of 150 we get R2 = 149 kohm.

For cutoff frequency equation assume-

R3 = R4 = 1000 ohm. Keeping in the equation of cutoff frequency we get C1=C2=158.11 nF.

Note :- The values can vary as per chosen resister values. The answer is not unique.

Answer :- 2) Thehe active high pass filter can be designed as shown below-

The same method can be used to find the values of resistors and capacitors. Equations are same for both LPF and HPF. Since in this questions values are differrent hence answer may not be the same as LPF.
