(b) Convert the numbers +26 and -26 to 2's-complement 8-bit simple binary. Tukar nombor-nombor perpuluhan +26 dan-26 kepada pelengkap 2 's perduaan mudah &-bit] (3 Marks/Markah) (c) The most common type of analog-to-digital (A/D) converter used in computerized data-acquisition system is the successive-approximations, which employs an interval-halving technique. Consider a 12-bit A/D unipolar successive-approximations converter, which has an input range of 0 to 10 V. An analog voltage of 3.29 V is applied to the A/D input. Simulate the successive- approximations converter process to determine the analog output. Jenis pemukar analog-ke-digital (A/D) yang paling blasa digunakan dalam sistem perolehan data berkomputer adalah penghampiran berturutan, di mana lanya menggunakan teknik separuh-jeda Pertimbangkan satu A/D pemukar penghampiran berturudan ekakutub 12-bit, yang mempunyai julat masukan dari 0 ke 10 V. Voltan analog sebanyak 3.29 V digunakan ke dalam masukan A/D. Simulasikan proses pemukar penghampiran berturutan bagl menentukan keluaran analog (7 Marks/Markah)

Answer 1

-2- to (en 6) Range of also compliment numbers is given by where, n is no of bits let, n=6 The range of 265-compliment numbers is -32 to +31 Hence, using 6 bits we can reposent +26 & -26 +26 opposentation - we know that representation of positive number is some in a's compliment ferm (ar) binary from - (+26) - 011010 -26 representation -26 - 2's compliment of (+26) a a's compliment of (011010) i's Compliment of (011010) + 1 - 100101 + 1 loolio CamScanner
