Second-Order FIR Damping Filter Exercises

1. With brightness set to $B=0$ and $t_{60}$ set to 1 second, measure and report the decay time for all notes `A' over the range of the piano keyboard. (A-440 is a sixth above middle-C.) Explain any systematic deviations measured. [The faust2octave utility can be useful for this exercise.]
2. Repeat the previous problem with $B=1$.
