11.1.1 Analog Circuit Properties复习一下模拟电路的几大特性，分节介绍。11.1.1.1 Continuous Signals模拟信号是连续的。如下图所示：描述数字信号就是：logical high and low voltages (V_H and V_L )rise and fall times (t_LH and t_HL )描述模拟信号是：amplitude (V_A )slew rate (SR)overshoot (V_ov )settling time (t_Settle )bandwidthphaseand others.11.1.1.2 Large Range of Cir
