Physics · Antennas and Signal Processing
In antennas, if S A is the input signal generated by the source at temperature T A , T E is the effective noise temperature of the receiver network, B is bandwidth, and k is Boltzmann's constant, then the output signal-to-noise ratio is given by:

- 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)✓
Correct answer
S/N = S A / ((T A + T E )kB)
