During each symbol, the phase either remains the same, encoding a 0, or jumps by 180°, encoding a 1. Again, only one bit of data (i.e., a 0 or 1) is transmitted by each symbol. This is an example of data being encoded in the transitions between symbols (the change in phase), rather than the symbols themselves (the actual phase).
A variable-length quantity (VLQ) is a universal code that uses an arbitrary number of binary octets (eight-bit bytes) to represent an arbitrarily large integer. A VLQ is essentially a base-128 representation of an unsigned integer with the addition of the eighth bit to mark continuation of bytes.
For example, if six bits are used to represent the number "00 1010" (decimal positive 10) and the sign extends operation increases the word length to 16 bits, then the new representation is simply "0000 0000 0000 1010". Thus, both the value and the fact that the value was positive are maintained.
Joel Spolsky and Jeff Atwood at MIX 2009. Atwood started a programming blog, Coding Horror, in 2004.As a result, he met Joel Spolsky. [8] In 2008, together with Spolsky, Atwood founded Stack Overflow, a programming question-and-answer website. [9]
the unit is called a nat, nit, or nepit (from Neperian), and is worth log 2 e (≈ 1.443) bits. [ 2 ] The trit, ban, and nat are rarely used to measure storage capacity; but the nat, in particular, is often used in information theory, because natural logarithms are mathematically more convenient than logarithms in other bases.
Bit manipulation is the act of algorithmically manipulating bits or other pieces of data shorter than a word. Computer programming tasks that require bit manipulation ...
