What is the required bandwidth of a low pass channel to transmit 1mbps by baseband communication?

The answer depends on the accuracy desired.
a. The minimum bandwidth, a rough approximation, is B = bit rate /2, or 500 kHz. We need
a low-pass channel with frequencies between 0 and 500 kHz.
b. A better result can be achieved by using the first and the third harmonics with the required
bandwidth B = 3 × 500 kHz = 1.5 MHz.
c. A still better result can be achieved by using the first, third, and fifth harmonics with
B = 5 × 500 kHz = 2.5 MHz

What you called a fiber optical cable in which the light signal follow a single path?
Baseband systems use digital signaling over a single channel. Signals flow in the form of discrete pulses of electricity or light. Figure 2.19 shows a baseband transmission with a bidirectional digital wave. With baseband transmission, the entire communication channel capacity is used to transmit a single data signal. The digital signal uses the complete bandwidth of the cable, which constitutes a single channel. The termbandwidthrefers to the data transfer capacity, or speed of transmission, of a digital communications system as measured in bits per second (bps).

What is Relationship between electrical and optical bandwidth for an optical fiber communication?
The electrical bandwidth refers to the frequency range that the electronic components in the communication system can handle, while optical bandwidth refers to the frequency range that the optical fiber can transmit. The relationship between the two bandwidths is important in ensuring that the data transmission is efficient and reliable. Matching the electrical and optical bandwidths helps to avoid signal degradation and distortion in the communication system.
What is a sentence for bandwidth?
The lawyer did not have the bandwidth to handle another case. The bandwidth was more than adequate to transmit the data quickly.
What is transmission bandwidth?
The frequencies which are used to transmit data.
What bandwidth do traditional modems use to transmit data?
2400 Hz
What is the purpose of broadband?
The bandwidth of a signal is related to how fast you can transmit information over that signal. Signals with large (or broad) bandwidth can transmit more information (data) in a given amount of time, so this results in faster download times.
Differences between baseband and broadband?
Baseband is a type of transmission that uses current to send a signal over the wire as digital wave. Broadband uses analog signal to transmit thru different frequencies, which increases the amount of data carried at one time.
What is redundent information?
Informational redundancy is the number of bits that it takes to transmit the desired message minus the actual number of bits that the message contains. In other words, it is the extra bandwidth required to send a message.
Difference between channel and bandwidth?
a channel is actually a path through which a signal of a particular frequency travels and bandwidth is the capacity of that path it tells about the number or range of frequencies which a path can carry
What is the difference bet copier wire and fiber optic in terms of internet connectivity?
Fiber optics usually allow a much higher bandwidth, so they are used to transmit large amounts of data. The end-user is usually connected to copper wire, since such a high bandwidth is not required for the end-user.
Explain if transmit baseband signal directly in a wireless system and why?
An antenna must be the order of magnitude of the, wavelength signal in size to be effective. Using only baseband transmission, FDM could not be applied and (Path loss, penetration of obstacles, reflection, scattering and diffraction. All the effects depend onthe wavelength of a signal.
