    hi << can anyone solve this qustions by multisim and upload the similation ?

    2- A digital car alarm circuit that takes 1 input (door car) and 1 output (alarm). The circuit will turn the alarm on if someone enters the car without resetting the alarm.
    When the driver is outside the car and the door is closed the alarm is “armed” but once he open it the circuit will wait 20 seconds for the driver to start the engine, if he didn’t then the circuit will turn the alarm on. The circuit should keep the alarm on until it is reset by the engine or the battery dies.
    Assume the clock is set to have one pulse for every 20 seconds.

    Is there any of your homework for which you are going to put in at least some effort of your own?
