第三章3-4行列式的完全展开式 3.4.1一些基本概念 定义给定n个互不相同的自然书,把它们按一定次序排列起来: ii2…in, 称为该n个自然数的一个排列。在上述排列中,如果有一个较大的自然竖排在一个较小的 自然数前面,则称为一个反序。一个排列中包含的反序的总数称为该排列的反序数。排列 …的反序数计作N(2n)。一个排列的反序数为奇数时,该排列称为奇排列

A function is a term used in mathematics and logic to denote a relationship between input and output variables. Each variable is restricted to binary (0, 1) values The relationship is the complex of three primitive functions (And \\Not\\Or)

6.1 Introduction The convolution sum description of an LTI discrete-time system can, in principle, be used to implement the system For an IR finite-dimensional system this approach is not practical as here the impulse response is of infinite length · However, direct implementation of the IIR finite-dimensional system is practica

Introduction Ideally, the system parameters along with the signal variables have infinite precision taking any value between -oo and · In practice, they can take only discrete values within a specified range since the registers of the digital machine where they are stored are of finite length

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]}
