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.
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.
Signal to noise ratio is the difference between the noise floor and the reference level.
the bandwidth and the 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.
In logarithmic quantization, one does not quantize the incoming signal but log of it to maintain signal to noise ratio over dynamic range. Dr Inayatullah Khan
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.
It can be calculated by simplifying the ratio between power of signal by power of noise
The Kenwood KDC-C471FM has a Signal-to-noise ratio of 100 dB
Signal to noise ratio is the difference between the noise floor and the reference level.
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.
Is that the signal interference + noise ratio?
Calculate the capacity of a telephone channel of 3000hz and signal to noise ratio of 3162?

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).

hi as we know noise temperature relate to noise figure as ................. T = T0(NF-1) where T0 is referance figure and NF is noise figure NF = (S/N)in --------- (S/N)out S/N is signal to noise ratio
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
