Homework Statement
A receiving system consists of an antenna with an effective noise temperature of
70 K. This antenna is connected to a microwave front end of noise figure 7 dB
via a feeder. The feeder’s specific attenuation function is 0.2 dB/10m. The actual
feeder length is 2 m. Calculate the carrier to noise power spectral density at the
output of the microwave front end if the received carrier power at the antenna
terminals is -100 dBm?
Homework Equations
I'm assuming it as Cmin = -174 + NF + 10Log10B + C/N
Where,
NF = Noise Figure,
B = Bandwidth, and C/N is a Carrier-to-Noise Ratio which is asked?
The Attempt at a Solution
Cmin = -110 dBm
Noise Figure (NF) = 7 dB & Struck up in knowing Bandwidth (B)
length of feeder is 2 meters,
feeder’s specific attenuation function is 0.2 dB/10m, What Next?
