Hi everyone
I'm afraid its another capacitor question from me....
I have a 555 square wave of around 1000 - 2000 hz (controlled by a potentiometer) that go to some speakers. Between the 12V and Ground I have a 470uF capacitor. When it is there, and when I turn the potentiometer handle, there is a nice smooth transition between the tones.
However, when I rip the capacitor out and vary the potentiometer, the difference in tones are CHUNKY and only change to a few fixed notes (musicians: it actually is a minor arpeggio!).
Why is there such a massive difference? Is it something to do with them smoothing out fluctuations?
Thanks for the help,
Muhasaresa
