Unipolar to Bipolar

Summing amplifier Av=9 (Was 3Vpp changing to 18Vpp) Signal + offset DC D from BC

One of many ways...

Ooops..not Av=9...Its Av=6 ..and the Mars probe bumps into a rock never able to go into reverse.. D from BC

Don't believe it- the aged fart actually posted an ASCII schematic!!!!

Now, now! This "aged fart" just returned from a seminar on CSI ;-)

** Groper Alert ! ** Use a capacitor to remove the DC offset from the original sine wave - gives a sine wave that has +/- 1.5 volt peaks.

Follow that with a amplifier stage with gain of 6.

Oh Buggerit!! You got there before me.....

Congrats, Jim, it's nice to post drawings that become a permanent part of the record.

Channel State Information, I assume. I've better things to do with my time.

Criminal Forensics "Road Scholar" 5-day seminar given by the MIT Alumni Association at University of California, Riverside... UCal's center for forensics education.

Very interesting stuff.

What "... better things to do with (your) time" ??
