Hi
Please find the attached file of solution, by seeing the attached fie you can analyze all the components
just changing the values.
The explanation of each component for the provided schematic is explained as below:
First stage: the first stage of the schematic is as shown below
In first stage we already know that, the output of the amplifier is unity gain by using this formula
A= -Rf/Ri
Here we calculate the gain by using each resistance value that is R1, R2, and R3 as input resistance (Ri)
and feedback resistance R4 (Rf)
I will show how it will work
A1 = - R4/R1 = 10k/10k = -1
A2 = -R4/R2 = 10k/10k = -1
A3 = -R4/R1 = 10k/10k = -1
So the overall gain across that network is unity and where C1, C2, and C3 acts as a low pass filter and its
lock DC. Its allows all the frequency and to find out the frequency around that network we know the
formula
F = 1/ (2*Ï€*R*C)
On substitution of R and C values in the above equation this lead to a value less than 45Hz and this is the
lower cut off point or in other terms -3db which is as shown in figure below and RC values of a low pass
filter and...
