An application of the channel capacity concept to an additive white Gaussian noise (AWGN) channel with B Hz bandwidth and signal-to-noise ratio S/N is the Shannon–Hartley theorem: C is measured in bits per second if the logarithm is taken in base 2, or nats per second if the natural logarithm is used, assuming B is in hertz; the signal and noise powers S and N are expressed in a linear power unit (like watts or volts ). Since S/N figures are often cited in dB, a conversion may b… WebAbout Channel Capacity • Channel Capacity (C) – the maximum rate at which data can be transmitted over a given communication path, or channel, under given conditions ...
