EMISSION AND DETECTION OF SIGNALS: Signals are emitted when they leave a visual, mechanical, electrical or electronic device and are received by an element that is capable of receiving (detecting), is ready and predisposed to receive said signals and codify them. The detection of signals in the case of telecommunications results from the tuning of the device to receive the frequencies that correspond to it (which travel through others in a main carrier call and were emitted by the emission device).
HEAT OR THERMAL ENERGY: It is the energy that is released by generating an alteration of an element that has its temperature in equilibrium, thus, by breaking that balance, said energy is released in the form of heat. This reaction may be due to a physical action such as rubbing or friction, or a chemical reaction (such as putting water in a piece of lime), or by increasing energy levels such as electricity in a resistor. What happens is that the mobility of the particles that make up the material increases, this translates as the increase in the kinetic energy of the particles.
NOISE EMISSIONS: These are all those generated by noise sources. They have a duration and intensity according to the source that generates them.
STATIC NOISE: Atmospheric noise is usually called this way, that is, that which is generated by the static that exists in the earth’s atmosphere, this usually manifests itself in the form of lightning, lightning, etc. Usually a signal responds to these noises in an increasing way from low frequencies in terms of 20MHz to 30 MHz.
TEMPERATURE: It is the thermal degree or level of the atmosphere, a material or body. It is measured with the thermometer. For example, room temperature, boiling water temperature, human body temperature.
WAVE INTERFERENCE: It is the superposition (also called addition) of two or more waves. The result can be a wave of greater size (constructive superposition) or smaller than the original ones (destructive superposition), according to the result of said superposition.
NOISE SOURCES: They are all those that emit a thermal, sound, microwave or any other wave that could affect the purity of the signal, that is, they produce waves that make the signal mix with others and it is necessary to filter it. In real life, a bandwidth filter is always needed. And a purification of the signal through specialized devices. The most common sources of noise are… Rain, hurricanes (Wind), storms, electronic devices that are operating nearby such as television, other radio or broadcast, a microwave, trucks that generate high vibration, high impact drilling elements , a mobile phone can be a noise generator for aircraft flight devices due to the wave emissions it generates, which is why it is requested to put it in flight mode.
