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 is different between baseband communication and carrier communication?
Baseband communication transmits digital signals directly over a communication medium without modulation, typically used in local area networks (LANs) where the entire bandwidth of the medium is utilized for a single signal. In contrast, carrier communication involves modulating a carrier wave to transmit information over longer distances, allowing multiple signals to occupy the same medium simultaneously through techniques like frequency division multiplexing. This makes carrier communication more suitable for broadcasting and long-range transmissions.
What do you call a fiber optic cable in which the light signals 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 is the bandwidth infrared?
Infrared bandwidth refers to the range of frequencies within the infrared spectrum that a device or technology can detect or transmit. It typically ranges from 300 GHz to 430 THz, allowing for communication and data transfer using infrared light.
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.
What is bandwidth in telecom spectrum?
In telecommunications, bandwidth refers to the range of frequencies that a communication channel can transmit, typically measured in hertz (Hz). It determines the amount of data that can be transmitted over a network in a given time frame. Higher bandwidth allows for faster data transfer rates and supports more simultaneous connections. Essentially, it is a crucial factor in the performance and capacity of telecommunication systems.
