Title: question about input signal(after folding) of comparator
Post by icekalt on Aug 5^th, 2009, 2:53am

hello,

How a signal look like when it enter one of the comparator in folding adc? is it still a sinusoidal or simply a constant after it is processed by folding circuit? see attachment..i'm confused since the input(Vf and vinc) of comparator X31 are both sinusoidal and i'm not sure how the comparator will make a decision..any help is really appreciated..thx
