Question

anyone who has started Homework 12....

Answer 1

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

Answer 5

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.

Answer 6

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

Answer 7

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)

Answer 8

some one asked me the value of pi. its always 3.14 buddy!

Answer 9

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

Answer 10

@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

Answer 11

what is ur value of v=?

Answer 12

v=5V

Answer 13

ok wait

Answer 14

what is the value of R in u r part 1

Answer 15

833.333333333

Answer 16

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

Answer 17

worked.. tks, bro

Answer 18

I didn't do the H12P2.. did you already do?
