Thanks, Jerry, Tim, You've been quite helpful. First let me say that I understand what he's trying to show - that undersampling can alias a signal down to baseband, or at least a lower frequency. I'm trying to use this book though to understand a few related things that relate to my work. Let me explain what they are, and therefore why this example confuses me (or, at least, why I'm not sure

Its been very helpful thus far, but there's one example that's driving me crazy. I've bounced this off another couple people here, but they seem confused as well. Luckily, I've found an open online source that has the text and pictures
