64 Kbps
Which channels are most suitable for real time video conferenceing digital quality audio and other services the require high bandwidth?
H channels
Voice grade bandwidthfor digital voice channels before compression is?
64 kbps
Will digital tv become anything like cable because it has extra bandwidth which can be used to broadcast more channels?
In reality, digital TV doesn't have extra bandwidth. It uses the same (or a little less) amount of bandwidth as standard NTSC television signal, but since it's digital in nature, they are able to multiplex up to eight TV signals within the same amount of transponder space. So yes, it can broadcast more channels.
Do digital TVs have decimal channels?
No. They have digital channels and may pick up analogue channels but there are no digital channels.
What's the difference between digital, regular, and HD cable?
Traditional cable is analog, which requires more bandwidth per channel. Usually you need a cable box to receive Digital cable which shall also include High Definition (720p) channels if you subscribe to them. You can also receive local HD channels with an antenna, but you'll need a new television that can receive digital channels or a digital converter box.
Why did the US change to digital?
Digital TV, you mean? It was to provide more bandwidth. Supposedly, programs were going to be sharper, clearer BUT of course networks and station owners went the shoddy route: more channels, each one no better (and usually worse) than the analog channels they replaced.
What is the typical bandwidth of a satellite transponder?
38 MHz. digital bit-rates vary depending on compression, modulation, typically QPSK. Expect at least 30 Mbps.
How do you get digital channels with your digital tv?
Go to the "set up menu" and click on SCAN DIGITAL CHANNELS.
What is the bandwidth of a T1 telephone trunkline?
A T1 telephone trunkline has a bandwidth of 1.544 Mbps. It consists of 24 individual channels, each capable of carrying 64 Kbps of data, which can be used for voice or data transmission. This standard is commonly used for digital transmission in telecommunications.
What does compression cause?
Compression causes a reduction in the size of data, allowing for more efficient storage and transmission. It can lead to loss of quality in lossy compression methods, while lossless compression retains the original data integrity. Additionally, compression can enhance performance by decreasing load times and minimizing bandwidth usage in digital communication. Overall, it is a crucial technique in data management and processing across various applications.
Why is throughput always less than bandwidth?
The main reason is that even when the full channel bandwidth is used there is always overhead required to manage the information transfer, so some of the total bandwidth will be consumed by this overhead. So only the remaining bandwidth is potentially available for throughput. This is true for both digital and analog communication channels. An example of overhead present in both digital and analog telephone communication channels are "alarm" signals used to report equipment failures to assist in equipment maintenance. Some examples of overhead in computer network channels are start bits, stop bits, parity bits, CRC codes, sync bytes, and packet headers. Also in many situations the traffic load is low for long periods of time so in those periods much of the potentially available throughput will not be made use of.
