    Hi guys!

    Could anyone help me out creating the 555 timer with a second-order cascaded bandpass filter? i'm trying to create it and simulate it on multisim and then on a breadboard.

    I'm a bit confused of where to start..

    Frequency 12khz
    Duty cycle should be 90-12 / 2 = 39%

    Cheers!
