Generally, magnitude comparators are digital circuits (IC's) which have two ports which accept, and latch two 8 or 16 bit binary numbers and have three single bit outputs: "Greater than, less than, and equal."
I have used these personally in several digital control systems.
I guess the "importance" is twofold. First, as you can use a single IC you simplify the hardware, but more importantly, for certain operations, they can be invaluable.
One simple use would be comparing the output of a free running digital counter to some fixed number. This fixed number, if derived from user adjustable binary hex switches, would allow control based on some adjustable terminal count. For instance, if the counter also fed into a D to A converter, and use the magnitude comparator to compare the two numbers, you now have a user adjustable ramp which can further be used with analog comparators to trigger many sorts of analog systems and also acts as a digital divider. One could create a temperature control for example using a sensor as one input but calculated in the digital domain, possibly with some microcomputer to make decisions.
I once used a very similar setup using two daisy-chained magnitude comparators in a telemetry system where the comparators monitored a counter which counted digital telemetry pulses and thus was the "memory of the number of plses and were used as a trigger for a setpoint alarm or maximum allowable user adjusted limit. As mentioned above, they can aslo be used to make a digital divider. For instance, using a free-running counter as one comparator input, and user switches as the other, you will get an "Equal to" signal for every x counts / y user input count. Very simple way to divide counts by any amount.
It's not so much "what's the importance" as that fully depends on the application, but rather the versatility and all the clever things one can use them for. I've designed more complex uses for them but my lack of recall of the details would not add to this answer but I did do some pretty cool, very specialized things which would have been difficult dto do without using the magnitude comparators. Only your imagination limits the cool things you can uyse them for.
Basically, Analog circuits like op-amps compare strictly in the analog domain. Magnitude comparators allow comparing purly in the digital domain. Combining the digital, D-to-A converters, and op-amps allows doing both simultaneously, if needed by the aplication.

magnitude comparator is a logic circuit used to compare the two binary numbers in order to determine the relationship between those quantities.
2 bit comparator = 1bit magnitude comparator +1 bit magnitude comparator if A>B =A(~B)(B bar); if A<B = ~A.B; A==B = AB + (~A)(~B); block of instruction shown above is for 1 bit comparator means if A>B ==true then High bit is set on (A>B) output. if A<B true then high bit is set on (A==B) output, If we cascade two 1 bit comparator then we can design 2-bit comparator...
magnitude comparator is a logic circuit used to compare the two binary numbers in order to determine the relationship between those quantities.
A magnitude comparator is a digital circuit that compares two binary numbers and determines their relationship, such as which number is greater, less than, or equal to the other. It typically has multiple inputs and outputs to indicate the result of the comparison. Magnitude comparators are commonly used in various digital systems for tasks like decision-making and control logic.
A magnitude comparator is an electronic circuit used to compare two binary numbers and determine their relative sizes. It outputs signals indicating whether one number is greater than, less than, or equal to the other. This functionality is essential in digital systems for decision-making processes, sorting operations, and various arithmetic functions. Magnitude comparators are commonly used in applications such as digital signal processing and microprocessor design.
Well, honey, to realize a higher magnitude comparator using lower bit comparators, you simply cascade multiple stages of comparators together. Each stage compares a subset of bits, and the outputs are then fed into the next stage until you cover all the bits you need. It's like building a ladder one step at a time to reach the top - ain't rocket science, just good ol' fashioned engineering.
The correct spelling is "comparator."
com[arator is apricision instrument it is used to compare the actual size of workpeice there r 4 types of comparator 1: mechanical comparator 2:electrical comparator 3:optical comparator 4:penumatic comparator
it is a mechanical comparator with magnification in range of 300 to 5000
A comparator is simply an opamp with a certain configuation of external circuitry ( a few components) that make it function as a comparator.
Magnitude and importance are two different things. I'll go with magnitude since I don't know how to judge importance of a trial. Lizzie Bordon, Scopes "Monkey" Trial, Nuremberg Tribunal, Julius and Ethel Rosenberg, O.J. Simpson...
