专利汇可以提供Signal transmitting circuit专利检索,专利查询,专利分析的服务。并且PURPOSE:To use a rotary transformer, which is used with a resonance frequency or lower, in a wide band by determining the value of a terminal resistance so that frequencies up to a frequency higher than the resonance frequency of the rotary transformer single substance can be used as a transmission band. CONSTITUTION:An emitter follower Tr1 which transmits a signal Ein from a preamplifier with a low impedance, an emitter follower Tr2 which receives the signal from the rotary transformer with a high impedance, and a terminal resistance R0 are provided, and an output signal E0 is outputted. The terminal resistance value R0 is set to satisfy R0>(L/Cni) /2 where Cin is the input capacity of a buffer amplifier and L is the inductance value of the rotary transformer viewed from the secondary side. With respect to a level A of the resonance point normalized with the value of a middle band, 60MHz band is realized by optimizing the value R0.,下面是Signal transmitting circuit专利的具体信息内容。
