How to solve this question

  1. May 6, 2008 #1
    i need to implement a sequential circuit that has two outputs
    the first recognizes 1,4,5,9
    the second one recognizes 12,13,14,15
    i need build this one using a PROM and a shift register

    what should i do...

    i think that a shift register is just a slow input line
    it proceeds in each Clock pulse were in normal line they data comes straight away.

    i was required to use it in the question

    i dont have any idea of how to build this thing

    when i tried to build the situation table
    i came to the conclusion that building it in the normal way with flip flops
    its impossible.its a 4 bit number
    there are lots of possibilities
    it would take me hours to write each one

    i think they intended for some other solution

    what should i do??
