Question

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 ____

a.

Pₘ=-184dBm+10log(Wₐ)+NF

b.

Pₘ=-174dBm+10log(Wₐ)+NF

c.

Pₘ=-174dBm+10log(NF)+Wₐ

d.

Pₘ=-184dBm+10log(NF)+Wₐ

Posted under Cognitive Radio

Answer: (b).Pₘ=-174dBm+10log(Wₐ)+NF Explanation: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.
