Batteries in parallel instead of series
Theoretically 1 and 3 could deliver the same energy(and power) and if I'm looking at two right(kind of confusing) you'd have a short. But practically 3 is better to use than 1 because there is no guarantee that the three batteries have the same discharge properties and can cause problems. see...- Odin42

Generating a rippled voltage supply
Probably, measure resistance from the center and the shell to the posts. If the shell goes to one and the center goes to the other then that should work. But as previously mentioned, I doubt the signal generator can source 1A.- Odin42

Generating a rippled voltage supply
I'd say put the center contact to the cap and the bnc shell to the resistor (even though this is all moot once you add an amplified(be it transistor or op-amp) to the circuit)- Odin42

C Book Recommendations for High School Students
I've always like O'Reilly books, I generally check to see what they have to offer before I check out anything else- Odin42

Generating a rippled voltage supply
The capacitor should block the DC offset, that's kind of what caps do(block dc). It depends on the frequency you are looking to do, but you'll probably want to use a very small capacitance value, otherwise you'll start dropping the ac output across the cap. Also in your other thread I...- Odin42

Microcontroller, FPGA, or CPLD for Precision Pulse Control?
Ultra precise can mean a lot of different things, first thing you need to specify is how precise. How long are the pulses you are trying to make? What type of precision do you need? Also it is nice to know what type of budget, how much time you have to do your project?- Odin42
