The power spectral density (PSD) of a noise process is given by
The noise is passed through a unit-gain ideal band pass filter, centered at 50 MHz and having a bandwidth of 2MHz.
(a) Sketch neatly the PSD of the output noise process.
(b) Determine the output noise power.
(c) Using the band-pass representation for the output noise process, sketch the PSD of the in-phase and Quadrature noise components, and determine their respective powers.
(a) 
(b) Output noise power = 20 mW
(c) 
(c) Output power = quad power = inphase power = 20 mW
