Hey guys.
So I am working on building a filter (yeah, I know, I'm experimenting), and it calls for a 10M resistor. I know these exist, but I sure as hell don't have something with such a resistance. However, I do have a 100k resistor. Is there any way I can multiply the number of ohms? I know they add, but I don't have enough resistors or room for that.
I've heard of people using FETs to multiply resistance, but no one actually says how that would work, and knowing how FETs work I can't see much of a way to do it.
Or, should I just buy a 10M resistor? That would be easier, of course, but I figure knowing how to multiply (and divide) resistance is a good skill to know, as most skills are.
