So, the total noise at a receiver which we I have understood it to be K T B F, K is the Boltzmann constant T is the ambient temperature B is the bandwidth and F is the noise figure that is how you have calculated and that is how we have done it.
तो, एक रिसीवर में कुल नॉइज़ kTBF है, जहाँ k बोल्ट्ज़मैन कॉन्स्टन्ट है, T परिवेश का तापमान है, B बैंडविड्थ है और F नॉइज़ फिगर है।
