H12P3:Our specification is that we want there to be two break frequencies for this filter: 12Hz and 17kHz. We also want midband frequencies, such as signals around 1kHz, to be amplified by about a factor of 2.
We have available a 1.2μF and a 470pF capacitor. We also have a variety of resistors between 100Ω and 100kΩ. However, our op amp really likes RS=20kΩ.
Your job is to fill in the remaining details of this design.Please help me nurali

HWP3 filter: 10Hz and 19kHz. signals around 1kHz, to be amplified by about a factor of 2. 0.68μF and a 390pF capacitor. resistors between 100Ω and 100kΩ. RS=20kΩ. pi=3.14
First find C1=0.68*10^-6 = 6.8e-7 (answer of part 4)
Then R1*C1=1/(2*pi*f) R1*C1=1/(2*pi*10) so R1= 23417
part 2)First find C2=390*10^-12 = 3.9e-10 (answer of part 5)
part 3) Rs = Rf = 20kΩ = 20000 Ω
part 6 : R3= R1
part 7 : R4= R2
part 8: c3=c1
part 9 : c4= c2
part 9 :Midband gain = (R4/R3)
