Question: gr_single_pole_iir_filter_cc

Hi All!

I would just like to ask what this line means. This has been taken from
the
doxygen generated documentation for gr_single_pole_iir_filter_cc:

[ H(z) = \frac{alpha}{1 - (1-alpha) z^{-1}} ]

Is it alpha /(1-(1-alpha)*z^-1)? Or is it 1/(alpha(1-(1-alpha)*z^-1))?

Thanks!

It’s latex style formatted math. \frac{X}{Y} = X/Y
