Hi all,
Sorry if this is dumb, or if it has been asked a million times:
If a have a circuit which is outputting a voltage which is logarythmically related to power (i.e. an output from a detector in a dummyload which rectifies the AC signal) in the range of 0-150v is there any way (other than getting out a calculator or creating a log scale meter - which ironically loses accuracy the more power you use) to convert this log scale back to a linear one? I have found plenty of reading material on log amps, but nothing about doing it this way around!
Was considering reducing the voltage down and using a PIC ADC, but my code writing abilities aren't all that. Just wondered if there were an easier of doing it than this?
As always any help greatfully recieved.
Thanks
