I am a teacher of English for IT. Please, help me! I do not know how to read $s(n), y(n), e(n)$ in English.
We are studying signal processing and the way a filter operates. The sentence is:
The incoming signal $s(n)$ is filtered or weighted in a programmable filter to yield an output $y(n)$ which is then compared against a desired conditioning, or training signal $y(n)$ to yield an error signal, $e(n)$.
Thanks for your help!
I would read it as "s n", but, especially for people who can't see what you're reading, "s of n" is probably best.
