Hello.
I wonder if some one can explain to me how the length of a ferrite rod with a wire wrapped round it
changes the behaviour of a LC tank circuit?
I have an AM receiver circuit that came as part of a kit. The capacitor can change from 0 to 160 pf.
According to the instructions I can tune this circuit down to 500KHz. I need to get down to 457KHz.
The inductor is 80 turns of wire on a ferrite bar. What is the ferrite bar used for?
I understand resonance and how to calculate it using capacitance and inductance.
IBut do not know how to construct the inductor to acheive the values i need.
Thanks for any help.
