Which type of message cannot be sent with the help of paging system? If $$Z\left( s \right) = \frac{{\left( {s + 4} \right)\left( {s + 9} \right)}}{{\left( {s + 1} \right)\left( {s + 16} \right)}}$$ is a driving point impedance, it represents an What is the ratio of thermal conductivity to electrical conductivity equal to? What is the shape of the cell present in the cellular system? The capacity of a band-limited additive white Gaussian noise (AWGN) channel is given by $$C = W\,{\log _2}\left( {1 + \frac{P}{{{\sigma ^2}W}}} \right)$$ bits per second (bps), where W is the channel bandwidth, P is the average power received and σ 2 is the one-sided power spectral density of the AWGN. For a fixed $$\frac{P}{{{\sigma ^2}}} = 1000,$$ the channel capacity (in kbps) with infinite bandwidth (W → ∞) is approximately
