Hello every one,
I have a question about a symbol.
We know that, complementary of a digital signal is shown by bar on that signal.
How about an analog signal. Suppose that we have a reference current of Iref, the output current is Iout=out1. Now we would like to have Iref-Iout. How can we display this value with respect to out1. May we mention by bar(out1 bar)?
