Neat. Thanks for sharing. With a XOR, you can't tell which input is higher frequency. I think you can fix that with a second XOR and a delay line.
I think 90 degrees of delay will provide the most information. At 10 MHz, that's 25 ns. I think that's about 15 feet of good coax. -- These are my opinions, not necessarily my employer's.
