Default If Amloop is LC circuit, what about RLC circuit ??

a damped LC ???
Does it make sense to introduce a R in the LC circuit and use it as
antenna ??
Does it change eg the Q ??? etc ...

I have tried to put formula's here
(look if they are right !
freq_low=Math.sqrt(1/(inductance*cap_high) - (resistance * resistance )
/ (4 *inductance *inductance))/(2*Math.PI)
freq_high=Math.sqrt(1/(inductance*cap_low) - (resistance * resistance )
/ (4 *inductance *inductance))/(2*Math.PI)

OK ???

A high R seems to lower the low freq, that's interesting ...



original formula for LC circuits: (put R = 0 in previous, and you should
get the same ....)
