3. determine the internal noise power in watts for a microwave amplifier that generates an equivalent noise temperature of 140 kelvins at an operating bandwidth of 500MHz.
should i use the formula N = kTB? if not, how should i solve the question?
thanks

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...

Question 1 The noise floor, also known as additive white Gaussian noise (AWGN), is a continuous noise level that appears over a wide spectrum when viewed in the frequency domain. True False 10 points Question 2 When considering the impact of impulse noise, we find that it is more devastating to a digital communications link, than an analog one. Therefore, error control methods should be used on all digital links. True False 10 points Question 3 When two transmitters operate...
