Im studying timer circuits...and it seems to be a bit confusing. Studying the 555 monostable multivibrator in particular the input and output pulses...it states that , with a negative going input pulse, the leading edge of the negative input pulse starts the leading edge of the output pulse which is positive...ok...fine but is this the same as saying - the output pulse starts when the input (trigger) pulse starts?
Or is it a matter of terminology...or how its worded...it seems like it should be simple but yet its confusing.Because it seems like I read other places where its not clear, sort of contradictory.
Also what if the input trigger pulse was positive...how would that relate to the output pulse? Would the leading edge of the input still start the leading edge of the output. I appreciate any thoughts, thank you so much
