Question:
In discussing thermal noise at the beginning of this chapter, we stated that at standard temperature (290 K) the white-noise assumption is valid to bandwidths exceeding 1000 GHz. If the temperature is reduced to 5 K, the variance of the noise is reduced, but the bandwidth over which the white-noise assumption is valid is reduced to approximately 10 GHz. Express both of these reference temperatures (5 and 290 K) in degrees fahrenheit.
