仅用两只晶体管的调频广播接收电路如图所示。该电路乍看起来不可思议,但它确实能正常工作。 两只晶体管组成一个耗电极少的振荡器,其振荡频率取决于由L和C1组成的谐振回路,L用18号线,4匝空心线圈(直径
Only two transistors FM radio receiver circuit as shown. The circuit looks magical at first glance, but it does work. The two transistors form an oscillator with low power consumption. The oscillation frequency depends on the resonant circuit consisting of L and C1, and L is replaced by a 18-wire, 4-turn hollow coil (diameter
