What signal to noise ratio is needed to put an T1 carrier on a 100 kHz line?

∙ 14y ago
The maximum data rate to T1 carrier is 1.544Mbps, so we have:
50000*log2(1+S/N) = 1544000
log2(1+S/N) = 30.88
1+S/N = 1976087933
S/N = 1976087932
So the signal-to-noise is 10*lg1976087932 = 93db

What do engineers use the signal to noise ratio for?
Signal to noise ratio is a measure of signal strength to the background noise. Engineers use the signal to noise ratio to improve digital signal processing.
In an amp What is better high or low signal to noise ratio?
Signal to noise ratio is the difference between the noise floor and the reference level.
What are the factors affecting signal to noise ratio?
If the SNR is too low, the signal cannot be distinguished from the noise. The signal must be boosted, or noise must somehow be removed.
Which factor affect data rate of a link?
the bandwidth and the signal to noise ratio
What is the Difference between noise margin and signal to noise ratio?
SNR = Signal Power / Noise Power, which is an indication of how well a receiver can distinquish a signal from random noise (non signal). The Noise margin is the measure in Db of how much better the SNR is than the SNR required for proper operation of a receiver. To a user this may be more valuable information, since the user may not know what an acceptable SNR is for his equipment.
What is the difference between SINR and CINR?
SINR - Signal to Interference and Noise Ratio CINR - Carrier to Interference and Noise Ratio difference between those to is difference between carrier and signal carrier is signal who doesn't "carry" any information . it must be modulated( by phase,freq or amplitude) and those changes convey information. carrier is unmodulated signal signal is defined as useful signal which carries information SINR is power of signal to power of interfenence and noise ratio
What is FM threshold effect?
An important aspect of analogue FM satellite systems is FM threshold effect. In FM systems where the signal level is well above noise received carrier-to-noise ratio and demodulated signal-to-noise ratio are related by: The expression however does not apply when the carrier-to-noise ratio decreases below a certain point. Below this critical point the signal-to-noise ratio decreases significantly. This is known as the FM threshold effect (FM threshold is usually defined as the carrier-to-noise ratio at which the demodulated signal-to-noise ratio fall 1 dB below the linear relationship given in Eqn 9. It generally is considered to occur at about 10 dB).
What do engineers use the signal to noise ratio for?
Signal to noise ratio is a measure of signal strength to the background noise. Engineers use the signal to noise ratio to improve digital signal processing.
How do you calculate Signal to Noise ratio?
It can be calculated by simplifying the ratio between power of signal by power of noise
What is the signal to noise ratio for the Kenwood KDC-C471FM?
The Kenwood KDC-C471FM has a Signal-to-noise ratio of 100 dB
In an amp What is better high or low signal to noise ratio?
Signal to noise ratio is the difference between the noise floor and the reference level.
Signal to noise ratio?
Noise signal is any signal which interferes with the main signal and does not give any important information.Signal should always be twice to that of noise.
What does CINR mean?
Carrier to Interference plus Noise Ratio, it's a measure of "true" signal strength at a receiver. In SNR, simply the signal strength to noise is measured; in CINR, distortions caused by interference patterns is also taken into account.
What is Sinr?
Is that the signal interference + noise ratio?
