4.4协方差和相关系数 问题对于二维随机变量(,): 已知联合分布 边缘分布 对二维随机变量除每个随机变量各自 的概率特性外,相互之间可能还有某种联系 问题是用一个怎样的数去反映这种联系 数 反映了随机变量X,Y之间的某种关系

Binary Code Natural Binary Coded Decimal (BCD) Decimal BCD group of four binary digits represent 0000 a single decimal digit

Digital system: entity can process, transfer and store any kind of digital signals is Composed of individual digital logic circuits which are designed to perform specified function

Karnaugh maps It is a matrix of squares. each square represent a minterm or maxterm from a Boolean equaTion N-variable karnaugh map have 2 squares The binary numeral on the sides of k-map is the variable coordinates

INTRODUCTION Level five Complex Systems, Function Units from levels Two through Four Level four More complex Function Logic Units, e.g. microprocessor Third IC level (VLSI) Level three Function Logic Units, e.g. adders, Second IC level counters, multiplexers (MSI and LSI) Level two Function Logic Units, e.g. gates, NOT, AND, NAND, EX-OR First IC level (SSI)

Let be the set of all input variables, X={, X1, .Xn} Let y be the set of all output variables, y={Y, 1 ...m} o The combinational function, F, operated on the input variable set, to produce the output variable set y. o The output is related to the input as
