3. Assume that Atmospheric noise is reduce exponentially for all frequency Vat-, t) = Aexp(--)cos(2nft) 0 where fo is just some reference frequency. a) Using some calculus, calculate the time averaged of this noise, < Vatm (f) >, you ref, is just sorne should take the time average At » peroid of the cosine wave. b) Using your result from a), make fo 1kHz show that going from a 1 kHz to 10kHz signal frequency will reduce the atmospheric noise by a factor of 1.23 x 10-4
