A detection system with a bandwidth of 250Hz has a signal to noise ratio of 12 when the detector is at room temperature. Calculate the new signal to noise ratio if the detector is cooled to -196 °C and the bandwidth is reduced to 10Hz for (a) thermal noise and (b) shot noise.
3. The quality of a received signal is often characterized by the signal-to-noise-ratio (SNR), which is defined as SNR 10 log As you might expect from this Signal power in watts KTB definition, the unit of SNR is decibels (dB). The term in the denominator is the noise power, and it is generally specified as an effective noise temperature T multiplied by the product of Boltzmann's constant (K) and the bandwidth (B) of the signal in Hz. Generally we like...
