Hi, Rick Would you please iterate more about why it's not a problem for analog signal? Maybe some mathematics would be very helpful to me. My understanding is if the spectrum is reversed, the signal shouldn't be the same. Thanks Sachi --- Rick Parrish <[EMAIL PROTECTED]> wrote: > Sachi wrote:

Hi, Eric and Matt I still can't understand the question I asked in July 26th's email. Hope you could take a look at the email titled "confusion about set_rx_freq()". My understanding is, if we get a "reversed version" of the spectrum, we eventually get the "conjugate version" of the signal in ti
