Logarithmic potentiometers

eeka chu · 30th December 2004, 01:24 PM

I didn't do advanced maths, so I've never really gone into Logarithmics properly.

What does it means when a potentiometer is labelled as being Log A or Log B?

A = log
B = Linear

Log B doesn't exist as far as I know.

Taper ------- Old Code------- New Code ------ Alternate
Linear -------- A -----------------B ------------ LIN
Log (Audio) ---- C -------------- A ----------- LOG
Antilog ---------- F ------------ N/A ---------- N/A
