This code is an adaptation of the Shawn's DSP Tutorials.

In particular, I started from this link. https://sestevenson.wordpress.com/2009/10/08/implementation-of-fir-filtering-in-c-part-2/ The first relevant change is in the initialization of coeffs variable done by exploiting constexpr described by the c++14 standard. The second change is on the number of samples that can be handled by a function call. Here we assume a single sample per function call.
