Modeling IF transformers in PSpice
Double_tuned IF transformers need to be sharp enough attenuation (Quality Factor) to adequately suppress equally_strong signals that are only 2_channel_spacing away.
WIth such attenuation of near_by stations, even city listening ot AM has some hope of succeeding.
Assume you want 30dB attenuation, double_tuned, for 20KHz carrier spacing
(2 of the standard USA spacing of 10KHz).
