the channel capacity (information in bits per second) is related to bandwidth and SNR by the relation
C= B[log(1+SNR) b/s
log is at the base 2
B= bandwidth of a channel
C= capacity in bits per second
SNR= signal to noise ratio.

What is relation between roll off factor bandwidth and bit rate?
The roll-off factor of a digital filter defines how much more bandwidth the filter occupies than that of an ideal "brick-wall" filter, whose bandwidth is the theoretical minimum Nyquist bandwidth. The Nyquist bandwidth is simply the symbol rate expressed in Hz: Nyquist Bandwidth (Hz) = Symbol Rate (Sym/s) However, a real-world filter will require more bandwidth, and the excess over the Nyquist bandwidth is expressed by the roll-off factor. Suppose a filter has a Nyquist bandwidth of 100 MHz but actually occupies 120 MHz; in this case its roll-off factor is 0.2, i.e. the excess bandwidth is 0.2 times the Nyquist bandwidth and the total filter pass-bandwidth is 1.2 times the Nyquist bandwidth.
What is the difference between NRZ L and Manchester encoding?
For NRZ we require large bandwidth,because transition will not occur in middle of bit.whereas in Manhaster encoding transition will occur middle of the bit so Data rate = Modulation rate/2 Regards, Dilip Prajapati
What is Full power bandwidth of an operational amplifier?
everyone, As far as I know the Full power bandwidth is the output bandwidth of the signal when it is made to obtain the max power from output suppose max output voltage is +/- 10 V as prescribed in the data sheet and the slew rate is 600V/u sec , then the full power bandwidth will be 600/(2*pi*10) that is 9.548 MHz
What is the symbol used in a formula to represent the rate of energy dissipation in an electric circuit?
"W" for watts, or wattage
What is RZ Signal?
Return to ZeroA type of digital signal where 1's and 0's are pulses of opposite polarity, but between each bit the line returns to the zero (ground) state. It is rather inefficient in terms of bandwidth/data rate, as each bit transmitted uses two baud (i.e. state changes).

Relation between channel capacity and bandwidth?
According to Shannon's Channel Capacity Equation: R = W*log2(1 + C/N) = W*log2(1+ SNR) Where, R = Maximum Data rate (symbol rate) W = Bw = Nyquist Bandwidth = samples/sec = 1/Ts C = Carrier Power N = Total Noise Power SNR = Signal to Noise Ratio

What is the difference between bandwidth and bit-rate in web steaming?
Bandwidth:- It is one characteristics that measures network performance is bandwidth. Bandwidth can be measured in two values:- 1. IN HERTZ 2. IN BITS/SEC. Bit Rate:- It is used to describes digital signals. the bit rate is the no of bits sent in 1s
What is the difference between the channel spacing and the transmission bandwidth?
Bandwidth is the measure of range or band of frequencies that a channel or path can handle at a maximum rate. whereas, throughput is the average rate of successful message delivery over a communication channel. and Goodput is simply the changing in throughput rate.
What is the relation between hemoglobin count and pulse rate?
There is relationship between pulse rate and hemoglobin count because as per your blood sensitivity you got your pulse rate high and low so this is true that there is relation ship between pulse rate and hemoglobin count.
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.
What is the relation of frequency and bandwidth?
Frequency is a measure of the number of occurrences of a repeating event per unit time. The bandwidth of a frequncy is simply the difference between the upper and lower frequencies.
What is the bandwidth of ASK?
We can use the law B=(1+d)*S where B is the bandwidth S is the signal rate d is between 0 and 1 (depend on modulation and filtering) Thanks
Why bandwidth is more in optical communication?
Bandwidth of an optical fiber determines the data rate.
What is the relation between pulse rate and breathing rate?
