In this paper we present the usage of Haskell and ClaSH in lectures on hardware design for students at the University of Twente. We discuss some examples from the field of digital signal processing, namely a high-pass filter and a low-pass filter. We demonstrate the continuous formulation of a filter, the discretized formulation, some possibilities to schedule it over time, and the mapping towards an FPGA. The advantage of using Haskell/ClaSH is that the underlying mathematical formulations that students learn in other courses, are readily translated into Haskell and mapped on an FPGA.
