## Main Question or Discussion Point

I am looking for literature in theoretical engineering that covers a topic of a signal which is both discrete and continuous.

For example ##x[n,t) = t/n## where ##t## ranges over ##[0,\infty)\cap \mathbb{R}## and ##n## is discrete, i.e takes values in ##\mathbb{Z}##.

I believe that this isn't covered in the usual books of Oppenhiemer, but I may be wrong.

Thanks in advance!
