So in the transverse direction Here are resistance is zero because Our resistance is zero right now in the superconductor. It's such a direction that our flocks producers the flux that the flux that's produced or potential cancel that change. I times are the negative sign indicates that are induced currents will flow. And this formulas is given to us through owns law right? We know icy cold severe are um so now we could rearrange this two negative one of our times flock steve flocks over DT now to isolate the dif logs over over DT they will be equal to negative. So our induction i is equal to electron motive force. So the law that describes this as it's called fairest law of electromagnetic induction. And we know the flocks is equal to the magnetic field being times our area. So the derivative of the flocks with respect to our time. ![]() Is electro motive force that's produced inside that loop is given to be equal to de flocks. So even if there are flocks up on magnetic field, there were area again is founded by a closed a close conducting loop. How many check bits are required? What fraction of signal bits are check bits? (d) Explain why this simple scheme fails if two errors occur in the same row or column. How many check bits will violate the "even-sum" rule? How does this information indicate that the error is not in the message, but in the check block? (c) Suppose that $N \times N$ message blocks are used instead of $4 \times 4$ message blocks. ![]() How many check bits will violate the "even sum" rule? How can this information be used to identify and correct the mistake? (b) Suppose a single-bit error occurs somewhere in the check block. (a) Suppose a single-bit error occurs somewhere in the message block. You should verify that this is true for the (message $ $ check) array shown here. Each 16 -bit message block is arranged into a $4 \times 4$ array, and the 8 check bits are aligned with the top row and left column of the message, as shown, with the 16 -bit message in the dark square in the lower right.Įach check bit is set so that there are an even number of 1 s in every column and every row (in those 4 rows and 4 columns containing message bits). Consider a signal consisting of 16 -bit message blocks accompanied by 8 -bit check blocks that is, $1 / 3$ of the signal consists of check bits. ![]()
