When I looked at equations for bandwidth, they state that resistance (or is it impedance) is a factor in the calculations.
Because the inductor and capacitor are the only two items that directly affect the frequency of the "tank circuit", (an inductor and capacitor appearing connected in parallel) is it possible that I can still obtain a reasonable bandwidth figure without factoring in the resistance?
it seems that now, the only way to calculate the resistance of the tank circuit is to measure it with a special DMM. My DMM's are junk and can't measure lower than 1 ohm. I'm 100% certain that a tank circuit measures less than 1 ohm.
So what is the absolute easiest way to calculate bandwidth if the only two values given were the inductor value and the capacitor value?
and if I need resistance, is it safe to assume 1 ohm?
