Answer:

2.783 * 10^-3 watts

Explanation:

calculate the maximum allowable input signal

= Dynamic range * sensitivity

Dynamic range is in decibels hence we have to take log  

∴ 65 db. = [tex]10log_{10} (DR)[/tex]

              = [tex]10 \frac{65}{10}[/tex]  =  [tex]10^{6.5}[/tex][tex]10^{6.5}[/tex]

therefore DR ( dynamic range ) = 31.6223 * 10^5

sensitivity = 0.88 nW = 0.88 * 10 ^-9 watts

therefore the maximum allowable input signal = ( 0.88 * 10^-9 ) * ( 31.6223 * 10^5 )   = 2.783 * 10^-3 watts
