离散系统零状态响应的直接确定

A direct method for finding the discrete-time system's zero-state response sequences

讨论了在常见典型信号作用下直接确定线性时不变离散系统零状态响应的一种方法。该方法无须先求出系统的单位冲激响应，再去求激励信号与系统单位冲激响应的卷积和，而是把求系统的零状态响应问题化为直接确定另一系统的单位冲激响应。这种方法比传统方法简单而且易于掌握。

A method of directly determining discrete-time system's zero-state response se-quences under the action of the common typical signals is discussed. This method need not prerequisitly to calculate the system's impulse-response se-quences but to transform the system's zero-state response into an event of de-termining another impulse-response sequences,This method is simpler and eas-ier to master than traditional one.
