The inductance of the side of the transformer connected to the tank circuit would be several times the inductance in the tank circuit, and changes to the overall inductance (parallelled inductances) of the circuit would be taken into account. Thanks ....sure you can. I think you noticed that sometimes the antenna is connected to a tap on the inductor, thus creating an autotransformer. The one thing to beware of is to make sure that the input impedance, reflected through the transformer is high enough, so as not to load the tuned circuit. it's NOT a match. If matched, the impedance of the transformer's secondary would be equal to the tuned circuit's impedance, thus lowering the Q of the tuned circuit to one half the original value. Saandy 4Z5KS |
