12 Questions
What is the bandwidth of a channel in terms of analog signal?
The range of frequencies that the channel can carry
What determines the maximum data rate of a channel?
The bandwidth available
What is the Nyquist Bit rate derived by Henry Nyquist used for?
For a Noiseless Channel
In what situation will the transmitted signal be attenuated or distorted?
When the channel bandwidth is less than the signal bandwidth
Why does a digital signal need to undergo a change before being transmitted through a bandpass channel?
To match the bandwidth of the channel
What did Jean-Baptiste Fourier prove about composite signals?
They can be decomposed into simple sine waves with different characteristics
What does bandwidth of a channel refer to?
The range of frequencies that can be transmitted through a channel
How is the Maximum Data Rate of a Channel calculated?
Based on Shannon Capacity formula
What is the bandwidth of a baseband channel with a lower frequency of 0Hz and a higher frequency of 100Hz?
100Hz
What type of channel is defined by having a bandwidth that is less than the bandwidth of the signal to be transmitted?
Narrowband channel
In broadband transmission, what is done to the digital signal before transmitting it through a bandpass channel?
Modulation
What happens if a signal with a frequency of 120Hz is transmitted through a narrowband channel with a bandwidth of 100Hz?
The signal will be blocked resulting in loss of information
Test your knowledge on the bandwidth of a channel and how it is measured in bits per second. Understand the concept of bandwidth for analog and digital signals, and the maximum bit rate supported by a channel.
