This GUI was designed to help users to better understand the Undersampling/Bandpass Sampling technique. While you're urged to follow the above link, to better understand this topic, a brief explanation follows:All of us, dealing with signal processing are familiar with the Nyquistd-deOCtShannon sampling theorem. According to it, in order to achieve proper sampling (and avoid aliasing) the sampling frequency must be at least two times the bandwidth of a bandlimited signal.From my experience most engineers tend to neglect the fact that Harry Nyquist theorem relates to Bandlimited signal, while keeping in mind just that in order to properly sample a signal with highest frequency f the sampling rate should be at least 2f. So do we need 11GHz sampling frequency to work with Wi-Fi? And in case of WiGig ~60 [GHz] signal we will need 120 [GHz] sampling rate? Fortunately this is not the case. In case of a signal whose Bandwidth in much lower than it's frequency BW/f

Requirements: No special requirements
Platforms: Matlab
Keyword: Bandwidth Fortunately Frequencies Ghz Highest It039s Keeping Lower Properly Rate Sample Wifi Wigig
