pls need help on hw 12??????

Question

anonymous · Answer

HWP3 - first 5 
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. 


1) 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

2)First find C2=390*10^-12 = 3.9e-10 (answer of part 5)
 
R2*C2=1/(2*pi*19*10^3)

R2= 21489
3) Rs = Rf = 20kΩ = 2000 Ω

Remaining answers HWP3
part 6 :  R3= R1
part 7 : R4= R2
part 8: c3=c1
part 9 : c4= c2
part 9 :Midband gain = -­(R4/R3)
