Hello, Will please anyone help me out of this, i want to know that can a uniform current no matter a.c or d.c be amplified. I am working on a experiment in which the current which will e induced by a photodiode will have to be amplified. I know that we can amplify A.C using transformers also amplification is also done in a t.v set. But the probem is we know that signals in both the transformer and t.v set are not uniform but in this experiment we do not know that will current indused will be uniform or non-uniform as it all depend on the frequency of the light and its intensity at the moment. any kind of help is really appreciated. Thanx.
