How is bandwidth of noiseless channels calculated?
How is bandwidth of noiseless channels calculated?
Bit Rate = 2 x bandwidth x l0g2 L In this formula, bandwidth is the bandwidth of the channel, L is the number of signal levels used to represent data, and Bit Rate is the bit rate in bits per second.
How many signals are needed in order for 265 Kbps to be sent over a noiseless channel that contains a bandwidth of 20 KHz?
We need to send 265 kbps over a noiseless channel with a bandwidth of 20 kHz. How many signal levels do we need? Explanation: 256000 = 2 × 20000 × log L = 6.625.
What is noisy and noiseless channel?
The exploration of protocols is split into those that can be applied for noiseless(error-free) channels and those that can be used for noisy(error-causing) channels. The first category of protocols cannot be used in actual life, but they serve as a basis for protocols for noise channels.
What is the channel capacity for bandwidth of 3 kHz and signal to noise ratio 30 dB?
For example, if a system has bandwidth B = 3 kHz with 30-dB quality of transmission line, then the maximum data rate = 3000 log2 (1 + 1000) = 29, 904 bps.
What is noiseless channel?
An idealistic channel in which no frames are lost, corrupted or duplicated. The protocol does not implement error control in this category.
How is the data rate limit calculated for noiseless channel and noisy channel?
Two theoretical formulas were developed to calculate the data rate: one by Nyquist for a noiseless channel, another by Shannon for a noisy channel. In this formula, B is the bandwidth of the channel, L is the number of signal levels used to represent data, and Bit Rate is the bit rate in bits per second.
What is the value of SNR for a noiseless channel?
Answer: The values of SNR and SNR dB for a noiseless channel are Example 3.32 We can never achieve this ratio in real life; it is an ideal. 94.
What is the maximum data rate for a noiseless 4 KHz channel?
1000 samples/sec
What is the maximum data rate? ANS: A noiseless channel can carry an arbitrary large amount of information, no matter how often it is sampled. Just send a lot of data per sample. For 4-KHz channel, make 1000 samples/sec.
