I have an exam coming up tomorrow and I was looking over the review sheet provided for us and I'm having some issues on what should be some rather simple stuff.
Converting binary address to hex and masking.
Here are the questions and answers, but I'm overlooking some simple stuff in regards to getting to the answers.
Converting binary address to hex and masking.
Here are the questions and answers, but I'm overlooking some simple stuff in regards to getting to the answers.
Im stuck here, I keep getting numbers like 24, and I'm not sure how to arrive at the answer of BACE. Which bit is the parity bit? Which 3 bits are the address and what bits are the data?A 16-bit signal was received by a smart MPI block and it consisted of a 3-bit address, a single parity bit and the remaining bits were data.
If the received packet was 1011101011001110, what is its HEX value? Enter only the 4 hex numbers.
________ BACE
I do not understand masking and we didn't cover that much of it....so I'm really lost here.What HEX value would mask out everything but the data from the received signal? Enter only the 4 hex numbers.
________ 1FFE
What HEX value would mask out everything but the address from the received signal? Enter only the 4 hex numbers.
________ E000
What HEX value would mask out everything but the parity bit value from the received signal? Enter only the 4 hex numbers.
________ 0001
