Hello,
The below picture is part of my design.
I regularly need to change the values of R1 and R2 in real circuit till get the best response of the circuit, but the values of those resistors must be the same at any time. I thought of using a doubled volume but after testing one of them with my ohm meter I noticed that the values do not change similarly (I had 3k for one while 500ohms for the other at a fixed arm point!).
Can everybody help me with a good and reasonable solution please?
I have to replace the resistors with a variable resistor till I get a good response from the circuit and then I'll use 2 fixed resistors for the final circuit, but for now I have to use something to change those values at the same time.
Thanks.
