1.	If Wais the receiver bandwidth and NF is the noise figure, the noise power of a noise limited receiver is given by the expression ____(a) Pm=-184dBm+10log(Wa)+NF(b) Pm=-174dBm+10log(Wa)+NF(c) Pm=-174dBm+10log(NF)+Wa(d) Pm=-184dBm+10log(NF)+WaThe question was posed to me in unit test.Query is from ADC Tradeoffs in division Technology Tradeoffs in Software Defined Radio of Cognitive Radio
Answer» The correct option is (b) Pm=-174dBm+10log(WA)+NF To EXPLAIN: If Wa is the receiver bandwidth and NF is the noise figure, the noise power of a noise limited receiver is given by the expression Pm=-174dBm+10log(Wa)+NF. The noise power of the noise limited receiver MUST be matched to power of the LEAST significant bit of ADC.
