    hi
    am anew electrical engineering student
    and i have a project in the course { digital and logic circuit design }
    and i havedea how to do it
    i realy want your help my prothers :D
    my project is



    {{{You are asked to design and implement (via simulation using Logic Works 4.0) a


    4-bit BCD arithmetic Unit. The operation is going to be one of 4 based on the value of the control selection (S1S0) according to Table I. The two operands (A and B) are 4-bits each and are selected from a combination of binary switches. The arithmetic output is to be displayed on a seven-segment display. You are allowed to use the following ICs only, and any other required basic logic gate(s): 7447, 7483, 74157 ICs only.



    Table I



    Bit Combination (S1 S0).............................................. Operation





    0 0 .......................................................................................... A+B
    0 1........................................................................................... - A
    1 0 ........................................................................................... - B
    1 1............................................................................................ 0

    HINTs:


    1. You can consult with your text book for part of the adder design.


    2. To display “-“ use the symbol that corresponds to binary input 1100 (12)10 in 7447 IC. Check the data sheet for this.



    Make sure to label all your design components, and show the input values as well as output values on a seven segment display. To learn more about the ICs check their data sheets on the web.}}}






    and i will be greatfull if you explain that for me please

    You really shouldn't post your email address publicly. A sad fact of life is spam bots search sites like this just for that kind of info.

    Go to the Google site - www.google.com - and type in "7447". Select one of the sites that come up to obtain the data sheet. Repeat for the 7483 and the 74157 IC's.

    Once you have all the necessary information, see if you can start to design the adder as required. Come back with specific questions.

    now i have questions
    he gave us a multiblixer with one control line and ask us to build a circuit with 2 control lines
    that confused me alot

    could help me with that
