A comparator is a device that accepts two analog inputs, compares the inputs, and produces a binary output that is a function of which input is higher. If the non-inverting (+) input is greater than the inverting (-) input, then the output goes high. If the inverting (-) input is greater than the non-inverting (+) input, then the output goes low. W [..]

1883, agent noun in Latin form from compare.

The standard (for example, another intervention or usual care) against which an intervention is compared in a study. The comparator can be no intervention (for example, best supportive care).

An investigational or marketed product (i.e., active control), or placebo, used as a reference in a clinical trial.

(IEEE) A software tool that compares two computer programs, files, or sets of data to identify commonalities or differences. Typical objects of comparison are similar versions of source code, object c [..]

In analog computing, a functional unit that compares two analog variables and indicates the result of that comparison. 2. A device that compares two items of data and indicates the result of that comparison. 3. A device for determining the dissimilarity of two items such as two pulse patterns or words.

A mechanical analogue computer used by sound-ranging to plot the fall of shot of counter-battery (CB) fire detected by sound-ranging microphones, compare it to the hostile battery location and compute [..]

A particular type of operational amplifier (op-amp) which has an output that is either on or off. It is a type of switch, but has two inputs, one for what is being measured and the other being a reference point. The comparator will normally switch on when the input is less than the reference. An example would be in a thermostat. Then input would be [..]

A device that compares one signal to another, usually the process signal compared to the set point or command signal.

java.util.Comparator is used to define a special sort order for a class. Use the ComparatorCutter to mindlessly crank out complete code for Comparables and Comparators. The code will help teach you th [..]

Bush's tape based-electronic cryptanalytic machines.

A comparator means a comparable employee who is doing the same or similar work as a part-time worker or someone on a fixed-term contract.

An electronic device that compares the voltages applied to its inputs.

An op-amp circuit that compares two inputs and provides a DC output indicating the polarity relationship between the inputs.

An investigational or marketed product (i.e., active control), or placebo, used as a reference in a clinical trial.

A component that compares two analog variables and indicates the result of that comparison [see Voltage Comparator]. A device that compares two items of data and indicates the result of that compariso [..]

A circuit whose output is a digital logic level that depends on whether its input signal is above or below a threshold at a specified time interval.
