By tuning to one side of the carrier, the receiver’s tuned circuit converts FM to AM. The bandwidth is about 200KHz so wideband FM stations can be demodulated by tuning the receiver to the most linear point of the response curve, rather than the top of the curve as one would for AM. In practice, this simply means tuning for clearest sound. … วงจรรับสัญญาณวิทยุ Super Regen Receiver ด้วยทรานซิสเตอร์เพียง 6 ตัว อ่านต่อ [...] [...] This little super-regenerative receiver is essentially an AM receiver, with “slope detection” used for FM.
