1. Please calculate the binary U2 fractional code representing the number 7,89 (minus seven point eight nine) on 18 bit word, with the precision better than 0,001%. [10]
   1. Determine the I & Q values of selected representation.
   2. What range of numbers we can represent (max and min value),
   3. What resolution you achieve finally and what is the maximal relative precision of this representation [minimal relative error]).
