  This symbol should be a system that processes an input signal u(t) and produces an output signal v(t). What I would like to write is: v (t) -> SquareSymbol-> u (t).

The only problem was finding a suitably small square symbol, which can be found in mathabx and imported.

A few tricks can make for defining also the corresponding left arrow avoiding code duplication. The square is positioned so that the distance from the arrow end to it is half than the distance to the arrow tip; this is of course reversed for the left arrow. You can vary this choice by changing {1}{2} into, say {1.5}{2.5} or whatever you think fit.
