What are the different derived quantities their description and their system international unit?
the quantities that are expressed in term of base quantities are called derived quantities e.g area volum speed force energy
What is the quotient of two quantities called?
The quotient of two quantities called a ratio.
What makes two quantities proportional?
Any two non-zero quantities are always proportional. If the two quantities are X and Y, they are proportional to X/Y.
A comparison of two quantities?
What is called a statement of comparing of two or more different quantities
What is a comparison between two quantities that do not involve time?
A ratio is a comparison of two quantities
What is an example of digital transducer?
A digital transducer is used to measure physical quantities and then transmit it as a coded digital signal. Examples include shaft encoders, digital tachometers, and limit switches.
What are digital transducers?
a transducer which can measures a physical quantities and and transmit the informations as coded digital signalsrather then as continuous varying current/ voltage.
How digital quantities are non linear?
A linear quantity increases at a constant rate whereas a digital quantity goes up (or down) in step. The difference is the same as that between a staircase and a smooth ramp (inclined plane)..
What is PDH?
PDH stands for Plesiochronous Digital Hierarchy. It is a technology that is used in telecommunications networks to send large quantities of data over digital transport equipment, like fiber optic and microwave radio systems.
What are the characteristics of digital analog and hybrid computers?
• digital computers work on discrete data representing quantities by encoding (e.g. integers, coded alphanumeric characters, coded floatingpoint numbers). • analog computers work on continuous data representing quantities by analogy (e.g. voltages, currents, shaft rotation rate, shaft position). • hybrid computers are a combination of digital & analog computers connected together to work as one machine.
Analogue and digital What is the difference?
This is the part of electronics consisting of such circuits which processes analouge quantities is called analogue electronics. And the part of electronics which provides the data in the form of a maximum and minimum voltage signals i.e. By two voltage levels only is known as digital electronics.
What are base quantities and derived quantities?
Base quantities are fundamental physical quantities that cannot be defined in terms of other physical quantities. They are used as building blocks in expressing other physical quantities. Derived quantities, on the other hand, are physical quantities that are derived from combinations of base quantities through multiplication and division with or without other derived quantities.
How are all quantities represented in a digital computer?
As encoded values composed of one or more bits. A small number of computers used trits instead of bits, but these were rare. Some computers of a new type currently being developed called quantum computers use quebits instead of bits. But the important thing common to all digital computers is the encoded values.This is in contrast to analog computers where quantities are represented as continuous values.
What are based quantities?
quantities which are not mademade from major quantities
Difference between analog and hybrid computer?
analog computers,continuous quantities are used. computation are carried out physical quantities such as voltage,length,current,temperature etc. the devices that measure such quantities are analog devices example voltmeter,ammeter.hybrid computer the best qualities of both the digital and analog computer. hybrid computers are best used in hospital. hybrid computers are also used in wheather forecasting.
Are most computers analog machines?
At this time, no, most computers are digital. However from the 1930s through the 1960s analog computers probably did outnumber digital computers as they were generally smaller and less expensive than digital computers.
What stores will sell cardboard jewelry boxes in large quantities or bulk?
There are several steps to using a digital micrometer correctly (preparation, taking measurements, and reading the meter). One site that may help with this is: http://www.tresnainstrument.com/how_to_use_and_read_digital_micrometers.html. You can also check with the manufacturer of your digital micrometer for a manual.
