What is the sampling rate of bandpass sampling?

The minimum sampling frequency for a 2-GHz bandpass signal with a bandwidth of 20 MHz is only about 40 MHz, as opposed to twice the highest frequency of 4 GHz.

What is a suitable sampling rate?

The Audio Engineering Society recommends 48 kHz sampling rate for most applications but gives recognition to 44.1 kHz for Compact Disc (CD) and other consumer uses, 32 kHz for transmission-related applications, and 96 kHz for higher bandwidth or relaxed anti-aliasing filtering.

What is the minimum sampling rate for the signal?

MINIMUM NUMBER OF SAMPLES

f. The sampling theorem states that a real signal, f(t), which is band-limited to f Hz can be reconstructed without error from samples taken uniformly at a rate R > 2f samples per second. This minimum sampling frequency, fs = 2f Hz, is called the Nyquist rate or the Nyquist frequency (6).
