Good Day,
While playing with some oscillators I discovered I can create an AC signal by decoupling the output of a 555 with a series capacitor and with the scope I made some interesting observations with questions to follow..
a) The amplitude of the crest and trough was a ratio of the duty cycle and at around 45% became a mirror image and the average voltage read zero; I understand the 555 astable puts out significant ripple and my question is.. how "much" of the DC signal is "converted" into AC as well as losses?
b) Concerning a perfect square wave at 50% duty: if it were to instantly transition from ON to OFF would the intrinsic associated turn on/off times of the components involved then become the dictating parameters of the signal since electrons are unable to stop instantly? Provided of course there is enough time before they reverse direction.
c) How much current is available from a series capacitor? Even with small capacitors I was able to drive a fair load with a single transistor.
Other insight into the subject is much appreciated
Cheers
