Nice simple one for y'all.

Both these need to have a 20db gain and should be operated from a +/-15v supply. Source is 1v 1kHz.

How do i get the gain right and where does the 15v bit go?

I have a sine wave coming out presently but the resistors are the wrong way round according to the equations are they not? Changint the values around produces a mess...

Any tips much appreciated...
