WebA bit-string is a sequence of binary digits (bits). The number of bits in the sequence is called the length of the value. A bit-string of zero length is called a null string. A bit … WebWhen the string starts with 101 and ends with 11, then there will be "2^4 = 16" strings (9-bits strings) Solution (d) If the 9-bits string has a weight of 5, then. From the 9 places to have digits, there are 5 places to have 1's. Therefore, there will be 9C5 = 126 strings (9-bits strings) n(A) = 9C5 = 126 strings (9-bits strings) The string ...

WebJul 11, 2015 · Since a bit consists of either the number 1 or 0, there are only two ways that the first slot can be filled or 2 n ways. Since there are eight bits, the answer would be 2 8 or 256. Part B is also relatively simple. There are a number of ways to solve this one. One way is to realize that is that you can fill up seven slots with two zeros, then 6 ...

WebA function f from A to B is an assignment of exactly one element of B to each element of A. We write f(a) = b if b is the unique element of B assigned by the function f to the element a of A. If f is a function from A to B, we write f: A → B.” Discrete Mathematics and its Applications by Rosen. a) f(S) is the position of a 0 bit in S WebSome definitions: A bit is either 0 or 1 (bit is short for “binary digit”). Thus a bit string is a string of bits. The length of a bit string is the number of bits in the string; the weight of a bit string is the number of 1's in the string (or equivalently, the sum of the bits). A \(n\)-bit string means a bit string of length \(n\text{.}\). We will write \(\B^n_k\) to mean the set of …

WebOct 26, 2015 · 01011 ^ 11001 means you look at both strings at each index and perform the logical operator on the two values. Here, we have "and", which gives true, or 1, if both values are true, and 0 otherwise. In the first place, we have 0 & 1 = 0. Next, we have 1 & 1 = 1, and then 0 & 0 = 0. Continuing in this fashion, we get 01001. WebMath; Other Math; Other Math questions and answers; 6.
