  2. 12-bit computing - Wikipedia

    en.wikipedia.org/wiki/12-bit_computing

    Many analog to digital converters (ADCs) have a 12-bit resolution. Some PIC microcontrollers use a 12-bit instruction word but handle only 8-bit data. 12 binary digits, or 3 nibbles (a 'tribble'), have 4096 (10000 octal, 1000 hexadecimal) distinct combinations. Hence, a microprocessor with 12-bit memory addresses can directly access 4096 words ...

    en.wikipedia.org/wiki/Gray_code

    The first few steps of the reflect-and-prefix method. 4-bit Gray code permutation. The binary-reflected Gray code list for n bits can be generated recursively from the list for n − 1 bits by reflecting the list (i.e. listing the entries in reverse order), prefixing the entries in the original list with a binary 0, prefixing the entries in the ...

  4. List of binary codes - Wikipedia

    en.wikipedia.org/wiki/List_of_binary_codes

    This is a list of some binary codes that are (or have been) used to represent text as a sequence of binary digits "0" and "1". Fixed-width binary codes use a set number of bits to represent each character in the text, while in variable-width binary codes, the number of bits may vary from character to character.

  5. Successive-approximation ADC - Wikipedia

    en.wikipedia.org/wiki/Successive-approximation_ADC

    If this analog voltage exceeds V in, then the comparator causes the SAR to reset this bit; otherwise, the bit is left as 1. Then the next bit is set to 1 and the same test is done, continuing this binary search until every bit in the SAR has been tested. The resulting code is the digital approximated output of the sampled input voltage.

  6. Computer number format - Wikipedia

    an 11-bit binary exponent, using "excess-1023" format. Excess-1023 means the exponent appears as an unsigned binary integer from 0 to 2047; subtracting 1023 gives the actual signed value; a 52-bit significand, also an unsigned binary number, defining a fractional value with a leading implied "1" a sign bit, giving the sign of the number.

  8. Effective number of bits - Wikipedia

    en.wikipedia.org/wiki/Effective_number_of_bits

    Effective number of bits (ENOB) is a measure of the real dynamic range of an analog-to-digital converter (ADC), digital-to-analog converter (DAC), or associated circuitry. . Although the resolution of a converter may be specified by the number of bits used to represent the analog value, real circuits however are imperfect and introduce additional noise and distor

  9. Flash ADC - Wikipedia

    en.wikipedia.org/wiki/Flash_ADC

    A flash ADC (also known as a direct-conversion ADC) is a type of analog-to-digital converter that uses a linear voltage ladder with a comparator at each "rung" of the ladder to compare the input voltage to successive reference voltages.
