Successful testing of the multiplier IC's

Today we successfully tested the multiplier IC's. Pre-filter, the output frequency was twice the input frequencies (as expected) and the amplitudes were very close to:

Vout = (V1*V2)/20

Post filter and DC coupled, the average output value was very close to:

Vout = (V1*V2)/20 * cos(Theta)
