Hopefully this should be a quick question.
I'm looking at a schematic for a lock-in amplifier (hat-tip: JILA), found here:
http://jila.colorado.edu/bec/BEC_for_everyone/lockincircuit.htm
Question: Do I assemble just one of the bypassing capacitor arrays (lower left corner) and then string it to all of the op-amps? Practically speaking, this seems problematic. I'm used to bypassing with a 0.1uF ceramic cap with short leads from power pins to ground on every IC. Here, it would seem that I would need lots of long wires (I'm working on a breadboard).
Or...is this just something that sits in distant corner of my breadboard and filters out high-freq noise from the +/- 15V power supply to ground? The op-amps powered by the rails now reap the benefits?
I can do without the Lumberg connector + Molex connector + Power LED, right?
Thanks!
