Explanation / Answer

please rate - thanks 3. (a) What is the value of the 8-bit binary number 10110010, if we treat it as (i) signed binary number    178 2+16+32+128 =    178 (ii) Unsigned binary number. Assume that we are working with signed magnitude representation. -50 sign =1 = negative magnitude = 110010 = 2+16+32=50 (b) Convert +75 and -75 to 8-bit binary numbers.  +75= 01001011   -75=11001011 in sign magnitude as sign magnitude for magnitude do repeated division  75/2=37 r 1 37/2=18 r 1 18/2=9 r0 9/2=4r1 4/2=2 r0 2/2 1 r 0   1/2=0 r1   readingbackward the magnitude is 1001011 (c) Using 8 bit ASCII code, write bit pattern forstrings      (i) AMS (ii) 252    AMS =0100 0001     0100 1101   01010100                                              252=    0011 0010    00110101   0011 0010
