Power and Noise calculations using decibel conversions
Convert the following numbers to dB with the correct dB units

a. A transmitter power of 250 watts

b. A received power of 2 x 10^6 watts

c. A noise temperature of 100 K

d. A bandwidth of 4.0 MHz

e. A radio receiver has a noise power N = kTB watts, with T = 100 K and B = 1.0 MHz. The value of k is 1.38 x 10^-23 J/K. What is the noise power in dBW?

f. If the radio in part (e) above receives a signal with power -100.0 dBm, what is the CNR (carrier to noise ratio) in the receiver?
