Chris,

Bob tried with a diagram and it did not come thru.  Another reply gave 
excellent web site for simple transistor circuits.

I'll try:

Using an NPN such as 2N3904 or 2N2222
1. ground emitter
2. from collector connect 4.7k res to +voltage (5, 12, etc)
3. connect 20k res to base and other end of 20k use as COR/COS input.

The inverted output will be off the collector where the 4.7k and collector 
connect.

73, ron, n9ee/r
