目的探讨调频(frequency-modulated,FM)成分在恒频/调频 (constant frequency-frequency modulation,CF—FM)蝙蝠下丘(inferior colliculus,IC)神经元恢复周期中的作用.方法在5只听力正常的大蹄蝠IC记录单个神经元的反应及CF和CF—FM声刺激模式下的神经元恢复 周期曲线.结果以CF刺激条件下的恢复周期曲线为对照,CF-FM声...
FM(FrequencyModulation)信号进行数字化解调实现方案。将前端预处理后的I/Q正交双路基带信号送入叉积鉴频器中,然 后利用差积和点积来求得信号的近似反正切值。方法克服了脉冲计数式鉴频法由于计算原理复杂导致不能适用高速信号 处理的局限,最大电路工作频率可达到206MHz,同时具有较好的抗载频失配特性。通过在Matlab上...
