A communication channel with additive white gaussian noise has a bandwidth of 4kHz and SNR of 31dB. Its channel capacity is?
20kbps
Is capacity of gaussian channel is equivalent to shannon hartley theorem?
Yes, the capacity of a Gaussian channel is indeed described by the Shannon-Hartley theorem. This theorem states that the maximum data rate (capacity) ( C ) of a communication channel with bandwidth ( B ) and signal-to-noise ratio ( SNR ) is given by the formula ( C = B \log_2(1 + SNR) ). It quantifies the limits of reliable communication over a Gaussian channel, making it a fundamental result in information theory.
What are causes of Intersymbol interference?
There are two processes:- 1 Bandlimited channel 2 Multipath propogation
What is AWGN channel?
An AWGN channel adds white Gaussian noise to the signal that passes through it.
How data rate affect channel capacity?
due to more data there will be more channels and having more information will take more time on a channel this why there will be more channel capacity
How error rate affected the channel capacity?
The error rate directly impacts channel capacity by determining the maximum amount of information that can be reliably transmitted over a communication channel. As the error rate increases, the likelihood of data corruption rises, which reduces the effective capacity of the channel. According to Shannon's capacity theorem, if the error rate exceeds a certain threshold, the channel's capacity can drop significantly, making it challenging to achieve reliable communication. Therefore, minimizing the error rate is crucial for maximizing channel capacity and ensuring efficient data transmission.
What is The capacity of a communication channel?
The transmission capacity is based on a formula describing the power between a transmitter and a receiver. The ratio of these two numbers and the formula describes the capacity of the channel.

The capacity of a communication channel is measured?
Bandwith
What are key factors that can affect channel capacity?
Channel capacity - It is the rate at which the data can be transmitted over a given path, or channel, under the given conditions. Key factors affecting the channel capacity are- Data rate- speed of data transmission measured in bits per second. Bandwidth – Maximum. Bandwidth, noise, and error rate.

Is channel capacity related to snr?
Yes, channel capacity is directly related to the signal-to-noise ratio (SNR). According to the Shannon-Hartley theorem, the maximum data rate that can be transmitted over a communication channel is proportional to the logarithm of the SNR. Higher SNR allows for more reliable transmission and thus increases the channel capacity. Conversely, lower SNR results in reduced capacity due to increased noise interference.
