Confusion about channel capacity definition and units

+1

−1

Why can the channel capacity C of the additive white gaussion noise (AWGN) channel be denoted in different ways and how do they relate to each other? Examples:

C = (1/2) * log2(1 + SNR)   [bit?]

source: wikipedia: Additive_White_Gaussian_Noise#Channel_Capacity

C = B * log2(1 + SNR)   [bit/s] with bandwidth B in Hz.

source: wikipedia: Channel_capacity#Example_application

SNR is the signal to noise ratio in both formulas and B is the bandwidth of the used channel in Hz.

Too many undefined variables, abbreviations, and missing context. (3 comments)
