    I am currently studying physics and have an assessment item on electronically generated sound. I was given a frequency of 440 Hz and i am using a 0.047 mf capacitor, with two resistors (33 kohm & 330 kohm). Using a 555 timer, we are expected to modify the square sound waves to more of a circular (sine wave). I know i have to use low pass filters, but im not quite sure where to put them on my circuit (which has already been built), i also have the capacitor and the resistors that I need to make a filter. Any help would be greatly appreciated

    Thank you
