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
