    At the moment) H12P1 A) Just V/i b) first find R2 = VS / i second the anwser is R = R2 - R1 (R1 is the awnser in a) c) I'm Trying LAB12 R1 (in Ohms): 1k C1 (in Farads): 1.59n R2 (in Ohms): 100k C2 (in Farads): 1.59n

    Our specification is that we want there to be two break frequencies for this filter: 10Hz 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 1.8μF and a 220pF 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. Q No 3 answers

    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

    H12 P1 c) Q: v=5v A=100, load resistance =500 Solve two equations to find value of vx vx/R=(vOut–vx)/500,with R=answer from Part1. vx=5–vOut/100 Solving two equations we get Vx Current = Vx / R

    @machu I did not undesrtand the c part of H12P1. I have these values: i=6mA A=100 R=833.333333333 VS=20V RL=500Ω

    ok then do this 1.6vx-vout=0 is your first equation 100vx+ vout=500 is your second equation add both will give u vx= 4.92 v i= 4.92/R=4.92/833.333= 0.005905512 this will be your answer please check yourself too.. tc and if correct click the best choice:) bye
