pls help me 2 solve this problem....
The block diagram of a wireless receiver frond-end circuit is shown in below. A noise source with a power of -70 dBm is applied to the receiver input. The physical temperature of the system is 270 K. The operating frequency band is 1850-1860 MHz.
(please take a look at the attached file...)
a) What is the equivalent noise temperature of the source over the operating bandwidth?
b) What is the overall noise figure of the receiver?
c) What is the equivalent noise temperature of the overall system?
d) What is the total power output (in mW) of the receiver?
