How'd a certain error percentage (let's say 2%) at a IC at the beginning would translate down a chain of ICs with certain Gains?
As the title says, I would like to know how a 2% error at IC#1 would translate down the chain of ICs (IC#2 gain is 10, IC#3 gain is 5) for the following diagram- Your insights are much appreciated.
