4line-2line encoder truth table 输出信号V是判断输入信号是否全为低电平0,为了区分当输入为4'b1000时,编码的结果和输入4'b0000时有相同的编码结果;根据真值表,分别画出输出x、y的卡诺图: 4-2编码器 卡诺图 分别根据卡诺图得到的布尔函数,描述出吗,描述出门级别的4line-2line 编码器,再通过较为抽象的RTL...
Table 1.Truth Table for the 74LS138, a 3-to-8 Line Decoder If a multiplexer or encoder hasN outputlines, then it has2Ninputlines. A common example of a decoder/demultiplexer IC is the 74LS148, which is a Low-Power Schottky TTL device that has 8 input lines and 3 output lines. The 7...
Figure 2: The 8 by 3 Priority Encoder The truth table below shows a number of input conditions as “don’t care” and are labeled as “X”. This means that the output is not affected by any condition of either “0” or “1” at these “X” values. From the truth table, it is ...
This functionality is advantageous when detecting shaft position of a multi-turn shaft. The encoding system is scalable so there are few limitations in deployment. Truth table logic is employed in a logic function designed to implement the foregoing attributes of the encoding system.Scalf Gerald W....

In this truth table, for all the non-explicitly defined input combinations (i.e. inputs containing 2, 3, or 4 high bits) the lower priority bits are shown as don't cares (X). Similarly when the inputs are 0000, the outputs are not valid and therefore they are XX....
an active state ("L" level), since it is not the MSB of the active operand input bits, it is regarded as an inactive bit ("H" level). Such an operation is equivalent to that a portion indicated by the symbol, (don't care) in the truth table in FIG. 1 is fixed at "1" ...
