I believe you really want the linear representation of channel numbers when
a log amp is used to collect the data. If so, divide the channel no. by 256
and use the result as a power of 10. '256' comes from the total channels
divided by the number of decades.

i.e. c
( --- ) c is the channel number
256
10
