>From: "Paul Schreiber" <synth1@...>A) Chris drinks too much and therefore often sees double!

>POP QUIZ!!!

>Why is Chris seeing a "doubled" waveform??

B) Proof by contraception:

1) Assume sine present at INPUT X.

2) Assume no input at Y

3) Assume small leakage between X and Y

Since the signal, X, is also present at Y, and since the RM OUTPUT is defined

as the sum frequency and difference frequency of the SINE wave inputs at X

and Y we see that the sum of (X + Y leakage) is equal to the sum of X + X =

2X which is one octave above X. While the difference (X - Y leakage) = (X -

X) = 0.

QED

But please don't call me POP.
