    Logic formulae

    Hi, I found below schematic in a theorie book. The given logic formula is: L=a . b . (b + c . d) (where b means b-not) I highly doubt that the logic formula and schematic correspond. Is the correct logic formula L=a . b . c . d for given schematic? Is L=a . b . (b + c . d) incorrect...

    Making a logic circuit with only 8 NOR Gates (4*2 Inputs and 4*4 Inputs)

    Hello everyone, I have a problem and I thought I should post it here because I can't quite get the hang of it. I was tasked to make a circuit that is made of only NOR-gates. Seemed simple at first but then the restrictions came in. The circuit needs to be made out of 4 NOR gates with 2 inputs...

    Combinational logic circuit input withdrawal

    How will the output of a combinational logic circuit change once the input is withdrawn? It will definitely change, how will it change?

    How to draw this logic circuit?

    Hello. This is JK flip-flop. I have to convert it into D flip-flop, that it does the same what JK does. Then I have to draw a logic circuit of D flip-flop. I don't know what to do, can you help me?
