Homework Help: Sketch output for 2-input AND gate

  1. Jan 20, 2012 #1
    1. The problem statement, all variables and given/known data
    Sketch the output waveform for the given circuit and inputs (see attachment)

    2. Relevant equations
    For AND gate: x = AB (multiply the inputs to get the output)

    3. The attempt at a solution
    attached is my sketch.

    How to multiply 2 waveforms?

    Your 2nd sketch looks correct. The AND of A and B will only be high if both are high at the same time.

    I guess you could call the AND function a multiplication, if you multiply the logical values (0,1). You can only get a 1 out of that multiplication if...
