HowdyAs I said we are assuming band limited signals. If you are talking about only one cycle of a wave form that is decidedly not bandlimited.
Nyquist shows that as long as you have incrementally more than 2 samples per cycle of your wave you are OK unless you are extremely unlucky, e.g. you have a signal whose freq is exactly a rational relationship with the sample rate. Since the rational #'s are sparse in the real #'s this is rare :)
And if you are bandlimited you have many cycles of your signal so you see the correct peaks, etc.
If you have a picture host you just put the URL for your picture in the 'Optional Image URL' when you post. You can also put in the HTML IMG tag, if you want it somewhere other than at the top of your post. If you don't have an image host, the Asylum provides inmate picture galleries for contributors.
