Bit

The smallest unit of information a computer can hold in its memory. A bit is always represented as a 0 or a 1 in binary code. The word is a contraction of "binary digit."

bit

a digit which takes the value zero or one and which can therefore be represented electronically by an off/on switch in a COMPUTER. Computers use groups of bits to represent numbers or letters for storage, transmission and processing of numerical or alphabetical data. Specifically, computers use various off/on permutations of eight bits to represent all numbers, letters and punctuation characters. Most computers use multiples of eight bits to handle data in this way and various eight-bit, sixteen-bit and thirty-two bit machines are available, the larger ones generally being able to process data faster.

We can display, at a glance, the impact on a single bit from all possible previous bit patterns. We take a long, received bit pattern and cut out each bit, synchronized with the clock.

So, assume a two's-complement CPU with integer words of 4 bits, and thus there are 16 possible bit patterns. For some applications it is useful to use this set of residues to identify bit patterns, the least-positive residue (LPR) system:

This simplifies the process of character recognition somewhat; all the OCR program needs to do is isolate groups of bit patterns on a page and decide which of the possible 128 ASCII characters (256 in the full ASCII set) is represented by each collection of dots.

To understand the operation of CIS, consider coherent sampling of a periodic signal such as a repeating bit pattern. The sampling clock derived from the trigger signal via a PLL is set to a frequency slightly lower than an integer submultiple of the bit clock.
