Conducting Excitation Decremental

Conduction of Excitation Decremental: Description and Application

Decremental excitation is a method of excitation in which the intensity of stimuli gradually decreases with each subsequent pulse. This approach to excitation was first described in 1871 by physicist Klaus Helmholtz, who proposed using the decremental method to measure the capacitance of capacitors.

Since then, the decremental method has found wide application in various fields, such as electronics, optics, biology, medicine and others. It is used to measure the parameters of systems, evaluate their performance and study their behavior under various conditions.

The principle of the decremental method is that with each subsequent stimulation pulse, the intensity of the stimuli decreases by a certain amount, which is called decrement. Thus, each subsequent stimulation pulse causes a smaller response than the previous one, and this allows us to evaluate the characteristics of the system and its ability to adapt.

In biology and medicine, the decremental method is used to study the functioning of the nervous system and muscles. For example, when conducting electromyography (EMG), the decremental method allows you to assess the ability of muscles to maintain contraction during repeated stimulation, which can be useful in diagnosing myasthenia gravis and other diseases associated with impaired transmission of neuromuscular impulses.

In electronics and optics, the decremental method is used to measure the parameters of oscillatory systems, such as tuning circuits of resonators and filters. It is also used to evaluate the quality of light waveguides and optical fibers, where the change in light intensity with each successive pulse allows the loss in the system to be assessed.

Thus, decremental excitation is a universal method that can be used to measure and evaluate various parameters of systems in various fields of science and technology. It provides information about the characteristics of a system and its ability to adapt under different conditions, making it an indispensable tool in research and applications.

Carrying out the excitation of decremental

Excitation carried out by the decremental method is aimed at removing the state of excitation by gradually reducing the forces acting on the excited organs. This type of method is used in cases where it is necessary to weaken or stop a psychophysiological reaction, for example, with angina pectoris, hyperkinesis, etc.

An example is the use of a depressant

Decrescendo is a continuous decrease in musical meaning from its highest point to its lowest point. This technique simulates a gradual increase in sound volume or a decrease in the key of a melody.

Quite often, musical literacy uses two musical terms in one expression: loud crescendo and quiet crescendo. They are translated the same way - “fast crescendo” or “rapidly increasing crescendo”. The second term is used to indicate that we are talking about a gradual increase in sound.

In fact, a word like “crescendo”, in addition to this meaning, has other interpretations, but they will be discussed in another material. In the meantime, let’s learn the meaning of a “loud crescendo”: in all theoretical and practical courses on the instrument, such playing techniques as stretched,
