Digital Communication Quiz

The upper limit provided by the theorem for reliable data transmission rate over Gaussian channels is the channel capacity, denoted by C.

The two important implications of the theorem for communication systems engineers are: 1) It gives the upper limit for reliable data transmission rate over Gaussian channels, and 2) It allows the exchange of signal-to-noise ratio for bandwidth.

For a given example where data rate is 10,000 bits/s and bandwidth is 3000 Hz, the signal-to-noise ratio is 9. If the bandwidth is increased to 10,000 Hz, the signal-to-noise ratio decreases to 1.

<p>Reducing the bandwidth from 10,000 Hz to 3000 Hz results in an increase in signal power from 1 to 9.</p> Signup and view all the answers

<p>The relationship between noise power and the two-sided power spectral density of the noise is N= ηB, where η represents the two-sided power spectral density of the noise in Watts/Hz.</p> Signup and view all the answers
