Why can the channel capacity C of the 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](https://en.wikipedia.org/wiki/Additive_White_Gaussian_Noise#Channel_Capacity)
- C = B * log2(1 + SNR) [bit/s] with bandwidth B in Hz.
- source: [wikipedia: Channel_capacity#Example_application](https://en.wikipedia.org/wiki/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.

Confusion about channel capacity definition and units
Why can the channel capacity of the 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](https://en.wikipedia.org/wiki/Additive_White_Gaussian_Noise#Channel_Capacity)
C = B * log2(1 + SNR) [bit/s] with bandwidth B in Hz.
