试用一片4位数值比较器[tex=3.571x1.0]oUGwHEVTmfyRDdRmJ6i2iA==[/tex]构成一个数值范围指示器，其输入变量[tex=3.071x1.0]RGN59LQ/a5zcnmaK3O1PPA==[/tex]为[tex=4.357x1.0]SGeA1SFjV+WoCPDGzBFkwQ==[/tex]码，用以表示一位十进制数X。当[tex=2.714x1.143]4ZRcdpm/A6Ex6mEFgzuFgA==[/tex]时，该指示器输出为1。否则输出为0。[tex=3.571x1.0]oUGwHEVTmfyRDdRmJ6i2iA==[/tex]功能表如表4.15所示。

用与非门设计一个数值范围判别电路。设电路输入[tex=6.071x1.286]GZbiT2P8T8KVyVUEWQpYyjIiVTkGekbnZrmhPI/Gp54=[/tex]为表示1位十进制数[tex=0.857x1.0]N7iCrOsS+NNEUUlnsYCi1g==[/tex]的[tex=4.357x1.0]SGeA1SFjV+WoCPDGzBFkwQ==[/tex]码,当[tex=0.857x1.0]N7iCrOsS+NNEUUlnsYCi1g==[/tex]符合下列条件时,输出[tex=1.929x1.0]vVfLuNZHFtqwkH3I5PXF9g==[/tex].否则输出为0。(1) [tex=4.5x1.143]+Zh7VhisZbdNCn4xgwsK0QuYQrgH/hJBD+8vhNE/JiI=[/tex];(2) [tex=2.714x1.143]8gOYC9pbwLnEKn/pKMOEow==[/tex] 和 [tex=2.714x1.143]PysoQXZUu2aAoOw8zK/A5A==[/tex]

设计一个组合逻辑电路，电路有两个输出, 其输入为[tex=4.357x1.0]SGeA1SFjV+WoCPDGzBFkwQ==[/tex]码。当输入所 表示的十进制数为 2、4、6、8 时, 输出[tex=2.714x1.0]9mt7DGjLVPrmGAH2beP3Rg==[/tex]; 当输入数 [tex=1.571x1.143]/ZZqb2UavqCa+84rehjjAQ==[/tex] 时, 输出[tex=2.429x1.0]/WKgK4mGhtRDtkryWa5wmw==[/tex]。 试用与非门实现电路并画出逻辑图。
