I am currently playing with the MC1496 with a view to using it as a double balanced modulator, ie. with the carrier optionally disappearing when no modulation is coming in. I am currently at the stage of trying to understand how it should be best connected...
Would the attached circuit work? It is derived from one on the data sheet, but redrawn for simplicity. Assuming low impedance signal and modulation sources, I am still worried that the presence of the 100 ohm resistors feeding DC bias to pins 1 and 4 would render the effect of the 47K 'carrier null' pot - null and void! Or am I mistaken?
Thanks for any help.
