A received signal has a bandwidth of 10 kHz and its power is uniformly distributed over this bandwidth. The bandwidth of the receiver is 15 kHz. The signal power density is 12 nW Hz ^-1 and the noise power density is uniform across the receiver bandwidth at 40 pW Hz ^-1 .

Calculate both the signal power and noise power.

Hence calculate the signal-to-noise ratio in dB.
