AM with log-antilog multiplier

Log/antilog multipliers have an output voltage that is proportional to the approximate product of the two input voltages. Since log/antilog works strictly in the positive domain, the carrier wave is phase shifted 180 degrees, multiplied by the signal voltage and inverted to account for the negative half of the carrier waveform. Adjust the DC source to modulate the amplitude of the carrier wave.

Great job, Josh, as usual 👍. I like how you got dual quadrant multiplication with the phase shift technique.
