Digital Electronics: Binary-Coded-Decimal to Seven-Segment Decoder

  1. Feb 1, 2005 #1
    This is one of the problems I have for homework:

    Consider a BCD-to-seven-segment decoder and suppose that the BCD data are represented by the logic variables B8, B4, B2, and B1. For example, the decimal number 7 is represented in BCD by the word 0111 in which the leftmost bit is B8=0, the second bit is B4=1, and so forth. a: Find a logic circuit based on the product of maxterms having output A that is high only if segment A of the display is to be on. b: Repeat for segment B.

    Here is my problem- I have no idea what the question is asking me for. The words "circuit based on the product of maxterms" confuses me and I just don't know what to look for. I am 100% sure if I knew what it was asking, I could do the problem but it doesn't say anything like that in the section explaining these decoders. Any help would be appreciated. Thanks in advance :)

    for anyone who may have been trying. Don't worry about it anymore and thanks. I finally figured it out. :)
