Notation
Description
In electronics, we frequently work with very small and very large numbers. For example, the propagation delay (i.e., the time it takes for the output to change after the input has changed) for a standard digital logic gate is 0.0000000095 seconds. Moreover, the clock speed of a typical personal computer is 2400000000000 Hz. Working with numbers of this magnitude, both large and small, can be cumbersome and prone to error. For this reason we use a power-of-ten notation. With a power-of-ten notation, any number, no matter how large or small, can be expressed as a decimal number multiplied by a power-of-ten. Scientific and engineering notations are the two most common forms of power-of-ten notation. In the field of electronics, engineering notation is the preferred notation because of the direct mapping between its powers and the International System of Units (the International System of Units is abbreviated SI from the French Système International d'Unités). The SI system is the modern form of the metric system. It is the world's most widely used system of units for science and engineering.
Conclusion Questions
1. Power-Of-Ten notation is important in engineering because it can easily express very large and small numbers.
2. Engineering notation is better for engineers because is counts in blocks of three. Using this notation, it gives less number for the user to deal with.
3. We do not use the femto scientific notation in engineering because it requires too many numbers. The amount of precision is not worth writing all of the numbers needed.
