Hi mates.
Albert's here. I'm new here and i'm seeking your helps regarding the
following.
I'm working on a project which involves the arithmetic operations (+,
-, X, /) on voltages. The project is to capture 4 voltages from 4
testpoints from a PCBA, ie A, B, C and D. After capturing the 4
voltages, we need to do the following calculations:
Result = ((A+B)-(C+D))/(A+B+C+D)
For the addition and subtraction parts, i've got the idea of using
summing amplifier and inverting amplifier to perform the functions. If
you have other suggestion, kindly share with me.
For the multiplying & division's parts, please give suggestion for the
circuit.
Thanks and hope to get your response soon.
Cheers,
Albert Leng
