    Correct, that was just a miss by me. Thanks again

    Simple Circuit using transistors

    the scope shows a 2V/div and the initial voltage is somewhere around 5v, where as the signal on the bottom is closer to 3.3v but I guess this shouldn't matter since the output is at 3.3v

    Simple Circuit using transistors

    Thank you again for your help, I ran the simulation and voltage b has a huge overshoot, is this normal?

    Simple Circuit using transistors

    I inserted a resister between the base of the transistor and CR circuit. The signal doesn't go to zero but to about half of the 3.3. Lastly, do I need a circuit at the output such as a RC circuit or just a cap?

    Simple Circuit using transistors

    Thank you again, Here's the circuit I came up with: the input pulse goes from 0 to 3.3 before the cap after R2 the signal drops to zero at the output the signal goes from 3.3 to 0 to 3.3 I just need to add something to the output to clean up the signal, RC circuit?

    Simple Circuit using transistors

    Here's the circuit I have so far. I would put a diode between the CR circuit to prevent the clamping?

    Simple Circuit using transistors

    Here's how the signals should look, a common emitter would give me the output signal, with a edge detection circuit? this would give me high then low output from the C-R.

    Simple Circuit using transistors

    Thank you for the response, The shape and polarity of the signal at the output in response to the input changing from 0v to 3.3v is:high low high The signal at the output is inverted and I don't need to change the wave shape. I am not sure about the amount of transistors, my first thought was...
