Counter type ADC: The D to A converter can be easily turned around to provide the inverse function A to D conversion. The principle is to adjust the DAC's input code until the DAC's output comes within ± 1 ⁄ 2 LSB to the analog input which is to be converted to binary digital form. Servo tracking ADC: It is an improved version of a counting ...
Instead of using the comparators in a flash ADC only once, the folding ADC re-uses the comparators multiple times during a ramp input signal. If a m -times folding circuit is used in an n -bit ADC, the actual number of comparator can be reduced from 2 n − 1 {\displaystyle 2^{n}-1} to 2 n m {\displaystyle {\frac {2^{n}}{m}}} (there is always ...
A delta-encoded or counter-ramp ADC has an up-down counter that feeds a DAC. The input signal and the DAC both go to a comparator. The comparator controls the counter. The circuit uses negative feedback from the comparator to adjust the counter until the DAC's output matches the input signal and number is read from the counter. Delta converters ...

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
An integrating ADC is a type of analog-to-digital converter that converts an unknown input voltage into a digital representation through the use of an integrator. In its basic implementation, the dual-slope converter, the unknown input voltage is applied to the input of the integrator and allowed to ramp for a fixed time period (the run-up period).
Geiger-Müller counter with dual counts/dose rate display measuring a "point source". The dose per count is known for this specific instrument by calibration. The count rates of cps and cpm are generally accepted and convenient practical rate measurements. They are not SI units, but are de facto radiological units of measure in widespread use.
The suite provides protection against an array of threats, including all infrared threat bands. The AN/ALQ-212 incorporates one or more infrared jam heads to counter multiple missile attacks. At IDEX 2013, Finmeccanica Company, Selex ES launched its Miysis DIRCM, suitable for all airborne platforms, rotary and fixed wing, large and small.
