WebDec 21, 2024 · The multiple of the sample rate must be the multiple of one end of the bandwidth, i.e. either 1.4Ghz or 1.6GHz. It works out well in our case, since 400MS/s*4 = 1.6GHz. So, we take two ADCs set up as an I/Q pair, each sampling at 400MS=/s. Then, 1.6GHz gets aliased to 0Hz, and 1.4GHz gets aliased to 200MHz. WebFor a minimum bit rate, the modulating signal must be sampled at the minimum sampling rate, i.e. at the Nyquist Rate. f s = 2f m. f m = Maximum frequency present at the …
