Hi all
I made a circuit featuring two 555s and the outputs connect together so when I run the signal through my ipod earphones I can hear two notes at the same time (yey!). I also made the DC signals go through a low pass filter there is a clear change in in the tone (which is good as it sounds more 'smooth').
But how can a low pass filter work with DC? Everywhere I looked on the internet AC was always used.
I would appreciate any help offered,
