The aim of this paper is to deal with uncertainty principles in finite-dimensional settings. Usually, an uncertainty principle says that a function and its Fourier transform cannot be both well concentrated. This paper present results of that flavor for unitary operators on \(\mathbb C^d\) and then applies those results to the discrete short-time Fourier transform.
