A 7-segment decoder drive the display in the figure. If the waveforms are applied as indicated, determine the sequence of digits that appears on the display.七段显示译码器如图驱动一个数码管。按照给定的波形输入,数码管上显示的数字序列为:http://edu-image.nosdn.127.net/1A8E664B8EA87EFB0E25183EB1226819.jpg?imageView&thumbnail=890x0&quality=100
举一反三
- 对于共阴极七段数码显示数码管,若要显示数字7,则七段显示译码器a~g应该为
- A BCD-to-7 segment decoder has 0100 on its inputs. The active outputs are (______). 0100是七段显示译码器的输入,则输出端为有效电平的是(______)。http://edu-image.nosdn.127.net/217FF551D935D8FE380EED80DD6A6137.jpg?imageView&thumbnail=890x0&quality=100
- The input waveforms in the figure are applied to a 1-bit adder. Determine the waveforms for the sum and the output carry in relation to the inputs by constructing a timing diagram(______).一位加法器的输入波形如图所示,请确定加法器的本位和和进位输出端的时序波形为(______)。http://edu-image.nosdn.127.net/B1C1396FD02DFE5B6BE996756934B85A.png?imageView&thumbnail=890x0&quality=100
- 【单选题】有关七段数码管的叙述错误的是: A. 当七段数码管全亮时可以证明七段数码管正常 B. 当七段数码管全亮时显示数字为8 C. 当七段数码管只有G段不亮时显示数字为0 D. 当七段数码管只有F段不亮时显示数字为9
- 对于共阴极接法的七段数码显示管,如果显示码为0000110,那么在数码管上会显示数字1。
