A receiver has a dynamic range of 65 dB. It has a sensitivity of 0.88 nW. The maximum allowable input signal is approximately:

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. =

              =  =  

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

the equation above shows how temperature f, measured in degrees fahrenheit, relates to a temperature c, measured in degrees celsius. based on the equation, which of the following must be true?

a temperature increase of 1 degree fahrenheit is equivalent to a temperature increase of

5

9

degree celsius.

a temperature increase of 1 degree celsius is equivalent to a temperature increase of 1.8 degrees fahrenheit.

a temperature increase of

5

9

degree fahrenheit is equivalent to a temperature increase of 1 degree celsius.

a) i only

b) ii only

c) iii only
