It's a chapter in a book that I have to study,but I dindn't understand the part about the impedances. thanks for the explanation!

Can someone tell me what does high or low impedances mean for the inputs and outputs for TTL logic,and how you can see that a port is high(low) impedant. And what if you connect other things to such ports?

is the cut-off frequency equal to the frequency of the pole?

My equation for A was wrong ,the nominator should be 1+jWCR2, so in this case C*R2=1/1000,right? by the way the plot is in hertz If I solve it like this my values are :111 ohm for R1 and 9 microF for C

thanks very much! Is it possible that C*R2 = 1/1000 en not C*R1 = 1/1000 ?

by the way,R1=1000 ohm

now you should be able to open the file I would really appreciate your help because I've got to find the solution very soon!

What is the theoretical definition of the phase shift?

you have to download the file and unzip it than you can open it. I've found the transfer function,but I've got to find two values out of it. (R1 is knowk,R2 and C1 aren't) I am unable to find the inverse function. Can you give me some more info please? thank's very much

Hi, I have got difficulties with the following:a simple RC circuit (scheme of the circuit and measurements attached). I measured out the bode plot and now I have to find the values of R and C ,but I don't know how. Can someone help me please.

I've got an R1 of 1K in parallel with an C and R2 in series.(Highpass) I've got the bode plot of the circuit measured out. Now I have to find the values of C and C2 ,can anyone help me? It is related to the cut-off freq but I don't know how.
