    Hello guys, Please i have a question on NOR Gate inverters. Anyone has a n idea on how they can be implemented in real life? as in a real circuit that would act as a NOR gate.

    Yes. Google CMOS NOR..

    Would the same NOR also work on the circuit below to change the weird pulse into a 0v or rather "no pulse" [​IMG]

    That is not a circuit.

    I'm saying would a NOR gate be able to change the weird pulse into zero?? or make the others zero and the weird one a "1"??

    No... if anything, you'd need a filter to filter out any additional frequencies beyond the fundamental sine wave in the rest of the screenshot...

    okay i get so by filtering it with a low pass filter it goes to zero right? which shows a missing pulse???

    I'm trying to see if i can change it to a missing pulse instead of the weird shape.

    None of these signals are pulses...

    I think you need to explain what this signal is...

    is it a sine wave with an abnormal signal coming in???

    Did you take that screenshot? You should know what you are looking at...it looks like another signal is being added to it at that point

    Is it mandatory for you to implement using NOR gate?

    Just use clipper/clamper circuit followed by comparator.

    How the hell are WE supposed to be able to tell YOU want it is!?!?! :rolleyes:

    And you are trying to do.... what? Get rid of the abnormal signal? Get only the abnormal signal?

    I think he may be wanting something like a missing cycle detector, based on this from post #8:
    See the attachment.
    Jaleela, is this the area where you want to develop a pulse? If so, you can detect the increase in time between zero crossings, or possibly with a phaselocked loop and some logic.
    What generates this waveform?

    Looks like the output of strain gauge or LVDT with equal but opposite displacements.

    Thank you all for the replies i think i kinda confused you, i am trying to make that certain pulse go missing instead of adjusting it dat was why i thought of a NOR gate?

    I wasn't suggesting that you wanted to adjust the waveform. I was illustrating that a cycle of the waveform looks like it is missing. I thought maybe you were trying to create a pulse at the location of the missing cycle.
    I have no idea why you think a NOR gate will do what you want, but then we still don't know what you want.
    Why don't you take your original waveform photo, and add (with something like Microsoft Paint) the waveform that you hope to get from the output of your NOR gate?

    Okay i have uploaded a picture, i want the abnormal pulse to go missing instead of big anyone understand what i mean?

    Ron - you're definitely a better artist!

    Yep.
    I think I see what (s)he wants, but I'm not sure.

    Jaleela, what is generating this waveform?

    And is this what you want?
