分析数字电路的逻辑功能时,我们通常假定输入信号和时钟脉冲都是理想的矩形波,所用的集成电路具有相同的参数,也不去考虑传输延迟问题。但实际情况远不是这样理想。如果我们在设计电路时忽视器件本身传输延迟等因素带来的影响,就往往造成电路正常逻辑功 When analyzing the logic functions of digital circuits, we usually assume that both the input signal and the clock pulse are ideal rectangular waves, and that the integrated circuits used have the same parameters and do not consider the propagation delay problem. But the reality is far from ideal. If we ignore the device itself when designing the circuit transmission delay and other factors, it is often caused by the normal logic circuit
