I hope this is the right place to ask this question......

I'm doing my final assessment and am dealing with logic gates etc. What I need to know is how do I type in the A B and C with the bar on top? Hope I'm making sense.

The other problem I have is how do I type in the gate symbols as well??

I would be most garteful for any suggestions Thanks guys JDR04

 

You don't.

You'd use /A*/B.
Or /(A*B).

Depends on the equotation, you have to add a large number of brackets in some cases.

The circuit diagram, you can use PAINT for simple one's, and insert a JPG.
For larger schematics, you'd use a PCB design software, or a simulator like Proteus to draw it. Or a CAD software if you are professional.

You should consider the Foxit PDF reader. It includes a plugin for Word! So it now can export to PDF with good results. Editing PDFs can be a pain, but Word is easy. Simply convert to PDF!

 

The following has two ways, which one will you use?
IF like /ABC then you can use 74LS10 - Triple 3-Input NAND Gate.

74LS10 datasheet.

If like /A/B/C then you can use 74LS04 + 74LS11.

74LS04 datasheet - Six Intverter, 74LS11 datasheet - Triple 3-Input AND Gate.

What does ANY of this have to do with the OP's question?

BTW, /ABC is poor form -- it's ambiguous. Does it mean (/A)(B)(C) or does it mean /(ABC). In general, the / has higher precedence than AND, as illustrated by your own second example since /A/B/C only means (/A)(/B)(/C) if you apply / first.

I think I do.


Basically an "overline : instead of an underline?


You mean a "not" symbol. You could use !A for not A or ~A (which is a bitwise not and maybe more appropriate). This is how it would be done in C and Java.

Thanks.
That is my fault, comparing to the second expression, I posted that /ABC actually is /(ABC).

 

insert a JPG.

No.
NEVER use a fuzzy JPG file type for a schematic. Use a very clear PNG file type instead.

 

This is an "overline" to denote "not".

According to Wikipedia this already exists as a unicode font:-

I haven't tried this, though!

You can do an Overline in Open Office. I would be surprised if you cannot do it in Word.

 

Follow these steps in MS Word to enter ~A:
1) Press Ctrl-F9
2) enter "EQ \x \to(A)" in the field between the braces (without the quotes; the area will be greyed out}
3) press Shift-F9 to complete.

To create other symbols, you can copy this one, paste and highlight it, right-click and select toggle field. Change the letter to whatever you need. This is limited to one level deep however. That is you cannot have something like ~(~A) or ~((~A)(~B)(~C)).

 

equation editor works for me, just type alt= to start new entry and type A\bar for example.

etc.

note that if you are using 2007, there is a newer equation editor but you need to save file as *.docx

Wow - thank you *so* much. I joined the site just to say that!

 

You can also use the insert>equation>accent and look for the overbar as described here.
