एंटीना में, यदि S A तापमान T A पर स्रोत द्वारा उत्पन्न इनपुट सिग्नल है, T E रिसीवर नेटवर्क का प्रभावी शोर तापमान (noise temperature) है, B बैंडविड्थ है और k बोल्ट्जमैन नियतांक है, तो आउटपुट सिग्नल-टू-नॉइज़ अनुपात (S/N) क्या होगा?

- 1S/N = (S A T A ) / (kB(1 + T E ))
- 2S/N = (S A (1 + T A )) / (kB(1 + T E ))
- 3S/N = (S A T A ) / (kBT E )
- 4S/N = S A / ((T A + T E )kB)✓
सही उत्तर देखें
S/N = S A / ((T A + T E )kB)
