If bandwidth of amplifier reduced then thermal noise in amplifier?
thermal noise willbe reduce
Which factor affect data rate of a link?
the bandwidth and the signal to noise ratio
What is the advantage of using external compensation for an op amp?
because it helps in noise reduction,bandwidth maximization
What is the connection between the bandwidth of a signal and the data rate that it represents?
The data rate (C) is equal to the bandwidth (B) times the logarithm base 2 of 1 plus the signal-to-noise ratio (S/N) (how much interference is introduced in the transmission of data)C = B x log2(1 + S/N)So your data rate is directly proportional to your bandwidth. If you increase your bandwidth, your data rate will also increase provided the signal-to-noise ratio isn't affected.
Why high frequency signal is more affected by noise compare to low frquency signal?
AS FREQUENCY INCREASE THE BANDWIDTH INCREASE. AS WE KNOW NOISE HAVE LARGER BANDWIDTH. SO ITS AFFECT HIGH FREQUENCY SIGNAL. BUT LOW FREQUENCY SIGNAL HAVE LOW BANDWIDTH SO IT IS LESS AFFECTED BY NOISE. ALSO WE KNOW QUALITY FACTOR= CUTOFF FREQUENCY / BANDWIDTH. SO AS FREQUENCY INCREASE B.W. INCREASE SO QUALITY DEGRADE. CUTOFF FREQUNCY AND THE TERM FREQUENCY (USED HERE) IS DIFFERENT. CUTTOFF FREQUNCY IS USED IN FILTER. PRABIR KUMAR SETHY prabirsethy.05@gmail.com
What is the relation between Noise Bandwidth and 3-dB bandwidth in ideal systems?
Bn>B3bn
If bandwidth of amplifier reduced then thermal noise in amplifier?
thermal noise willbe reduce
What factors control the voltage of a Johnson noise source?
It is the bandwidth, the temperature, and the resistance. Look at the link: "Calculation of Noise voltage: Thermal noise".
Which factor affect data rate of a link?
the bandwidth and the signal to noise ratio
What is shanon capacity?
digital bandwidth = analogue bandwidth * log2 (1+ SNR) where SNR = strenthe of signal power/ strength of noise larger the SNR it is better.
What is the relation of signal to noise ratio and signal bandwidth?
C=blog(1+s/n)
What is the Limitation of communication system?
1.Amplitude 2.bandwidth 3.Noise 4.Frequency
Advantages of large bandwidth?
A very usefull advantage is the exchange of SNR(signal to noise ratio) with Bandwidth... as on increasing the bandwidth the power required for transmission get reduced to a great extent.. is given by the formula SNR2 ~ (SNR1) B1/B2 AS we can see on increasing the bandwidth the SNR is reduced greatly
What are the factors affecting the bandwidth of radar?
Size of the target Effect of multiple targets Noise System Requirements
What is the advantage of using external compensation for an op amp?
because it helps in noise reduction,bandwidth maximization
What is the connection between the bandwidth of a signal and the data rate that it represents?
The data rate (C) is equal to the bandwidth (B) times the logarithm base 2 of 1 plus the signal-to-noise ratio (S/N) (how much interference is introduced in the transmission of data)C = B x log2(1 + S/N)So your data rate is directly proportional to your bandwidth. If you increase your bandwidth, your data rate will also increase provided the signal-to-noise ratio isn't affected.
