I have a very few background in signal processing but I want to apply
a frequency-weighting formula to a signal.
I have the details of that frequency-weighting as bellow:
Freq. Band #          Freq. (Hz)             Wm (dB)

i am solving Helmholtz equation for a rectangular waveguide using
Finite Element Method with a Fortran code.
Governing equation is
del ^ 2 (p) + k^2 (p) = 0

I hope you feel sorry for me as I'm feeling sorry for myself - I'm selling
my MLSSA system.  This has been a good companion for about 15 years, but the
display on my portable PC with a full length ISA slot became unreliable, so
it had to go.  It would be ideal for a fixed ...
