In question no. 29.
Option 3 ( SV) is not part of both IMEI and IMEISV..
Also the new IMEISV doesn’t have FAC.
I believe option 4 as the answer stands wrong here.
Yes, you are correct for option (3). For FAC (a 2 digit Final Assembly Code), many of vendor still use them.
In que no 5
CDMA is a digital technology and does not involve analog-to-digital conversion during transmission. The signals are digital from the beginning and are spread over the frequency spectrum using unique code sequences.
Acc to this 4 option is correct na..?
CDMA employs analog-to-digital conversion (ADC) in combination with spread spectrum technology
