A communications system features a channel containing additive white Gaussian noise. This white noise, band-limited to 0-10MHz, is passed through a perfectly rectangular filter of bandwidth 18 kHz, gain 3dB, and center frequency 455 kHz. If the original white noise has a normalized average power of 4W, what is the noise power after it has been passed through the filter?
