[sdiy] AD633 Ring Mod Querie

[Jim Patchell]

    Making a Ring Modulator from an AD633 is (fortunately) relatively
simple.

    First, go to the Analog Devices Website,
http://products.analog.com/products/info.asp?product=AD633

    Download the data sheet.  Turns out, a ring mod is just a
multiplier, which is what the ad633 does.  You will find that you don't
need a lot of external components to do the job.  One thing you will
want to add are the x and y offset pots, so that you can null out the
carrier.
