I have read your answer but I have a doubt. If I change alpha value, for example
putting 2^-10, according to me, it is not correct to change all [25:10] to
[25:9] because writing

"over_count = over_count_int[25:9]" and "rssi = rssi_int[25:9]"

I lose MSB. Instead, if I want to change alpha value, for example 2^-13, how can
I do?
I sent you my attached solution. In my solution, "input [4:0] alpha" indicates
the shift which will do. Is correct my solution?

Thank you very much.
