To create an 8-bit by 4-bit binary multiplier in Multisim, one must first develop a truth table that outlines the multiplication process. The multiplication of two binary numbers follows a similar principle to base 10 multiplication, where each digit of one number is multiplied by the entire other number and then shifted accordingly. The example provided illustrates how to multiply binary numbers by breaking down the process into manageable steps and summing the results. While this method is conceptually simple, it is not the most efficient approach for digital systems. Understanding these foundational concepts is crucial for designing the circuit in Multisim.

hi all,
new here, so sorry, but how do i make a binary multiplier in multisim?
is there a specific chip... or...?
i need to make an 8 bit x 4 bit multiplier

Can you create a truth table for a binary multiplier? After you have the truth table, can you create a circuit to produce the same truth table?
 
How do you multiply 2 numbers in base 10?
you multiply the top number by the first digit of the second number.
you then multiply the top number by the second digit of the second number, and multiply it by 10.
continue as needed.
the add all of the numbers together...

well its the same thing with digital systems.

\,1110
x1101
1110*1 (shifted by 0) +
1110*0 (shifted by 1) +
1110*1 (shifted by 2) +
1110*1 (shifted by 3) +

add them together and you get
10110110

that is the simplest conceptual way to multiply digital numbers. now it is not the most efficient way.

Thread 'I thought it was only Amazon that sold unsafe junk'

I grabbed an under cabinet LED light today at a big box store. Nothing special. 18 inches in length and made to plug several lights together. Here is a pic of the power cord: The drawing on the box led me to believe that it would accept a standard IEC cord which surprised me. But it's a variation of it. I didn't try it, but I would assume you could plug a standard IEC cord into this and have a double male cord AKA suicide cord. And to boot, it's likely going to reverse the hot and...
