What is the principle of superposition?

In physics and engineering, the principle of superposition is an additive feature of any linear function or system. Due to the calculated or measured outcome of the input variable, if one or more is separated, other variables will be used at the same time, the resulting net result will be equal to the addition of the relevant individual results of each variable. Simply put, its basic concept can be expressed as follows: If the input and results to the X and output output B is y, then the superposition of both inputs A+B will result in the corresponding X+Y output. One of the reasons for the term "superposition" is that the principle refers to a specific place and time. Due to the changing status of active systems, there are superposed inputs and output of positioning and measurement.

The superposition principle can be used on linear mathematical functions such as algebraic equations. When some of the input variables are influenced by the scales, for example at a constant coefficient of Math's quadratic equations, it isThis function considered both linear and homogeneous. For the above example, if known Skary 1 and 2 are applied to the input variables 1A+2b, the superposition is transferred to the output 1x+2y. The combined output is often called the sum.

Many mechanical and electrical products, systems and processes are designed to be linear. If the knob is turned clockwise, the volume will increase. In all the simplest devices, however, most systems are complex and affected by many variables. They are rarely, absolutely linear. While the principle of superposition is a convenient and useful tool for modeling and analysis of systems, it is only considered to be optimal approximation of operating conditions in real life.

Among the linear systems that have the most benefit from the application of the principle of superposition are those that use wave energy.Vukové, light and other electromagnetic radiation also have a strong stronger radiationA additive qualities. The form of the wave itself can be described as a linear equation. According to the principle, two or more waves of a certain height or amplitude occupy the same space and time will be converted into one wave whose amplitude is the sum of the original amplitude of the waves. Similarly, light wavelength for color red, when superpacted for green, will be additively transformed to a wavelength corresponding to yellow color.

This principle of superposition is the basic technology of headphones for holding noise. The microphone analyzes the wave of the ambient sound such as the low rumble of the aircraft engine. The speaker restores the same wave shape and is moved to the system before adding this sound. When the amplitude of the sound waves of the engine with a representative value of 1 coincides with the added court, the equivalent value of -1. Their effect of their sum is zero.
