Question

Shannon's law

Answer 1

This is what I did, but that just doesn't seem to make any sense, plz help...

\[C = B \log_{2} (1+\frac{ S }{ N})\]
\[1 = 1 \log_{2} (1+\frac{ S }{ 2})\]
\[1 = \log_{2} (1+\frac{ S }{ 2})\]
\[\log_{2} 2 = \log_{2} (1+\frac{ S }{ 2 }) \]
\[1+ \frac{ S }{ 2 } =2\]
\[\frac{ S }{ 2 } =1\]
\[S=2 mW\]
