The complex envelope of a passband signal is useful because it
Answer: A
Writing a passband signal as a complex envelope times a carrier exponential strips out the carrier and leaves a low-frequency complex signal carrying all the information, which is why simulation and digital signal processing work almost entirely in that representation: the sampling rate need only suit the bandwidth, not the carrier frequency. It changes no signal-to-noise ratio, since it is a representation rather than a processing gain. Filtering is still required. And nothing about it alters the statistical character of a signal.
