Objective-Determination- of realizable transfer function G() approximating a given frequency response specification is an important step in the development of a digital filter If an IIR filter is desired, G() should be a stable real rational function Digital filter design is the process of deriving the transfer function G

2.1 Discrete-Time Signals: Time-Domain Representation Signals represented as sequences of numbers, called samples Sample value of a typical signal or sequence denoted as x[n] with n being an integer in the range-oo≤n≤∞ x[n] defined only for integer values of n and undefined for noninteger values of n Discrete-time signal represented by {x[n]}
二章习题课 例题一、如图所示的构件,B为中间铰,受载荷如图所示。 求:A、C处的约束反力。 q M A a a 〔思路 1、在解题前,先回顾一下固定端约束的情形。分别以旗杆、墙上钉的铁钉等,介绍其约 束情况(反力的个数) 2、需要求解的未知数为4个,只选取一次研究对象不能解决问题,需要补充方程。故可 以考虑先选取BC为研究对象,在以整体为对象,即可求解。 解)
