Acoustic pressure
Adjective and noun
It is the movement in the air caused by sound waves, causing an alternating variation in its static pressure small variations in atmospheric pressure.
Example: An example would be the sound of an airplane engine which generates an acoustic pressure, what we hear as noise
es: Presión acústica
Analog frequency
Nouns
It is a type of signal generated by some type of electromagnetic phenomenon, which is represent a continuous mathematical function in which its amplitude and period are variable as a function of time.
Example: An example would be when you have a sine wave, whose shape repeats over time and increases its value with a positive electrical sign (+) during half a cycle and then decreases it with a negative electrical sign (-) in the next half cycle.
es: Frecuencia analógica
Continuous-Time Signals
Adjective
A continuous time signal is a function that is continuous, meaning there are no breaks in the signal. For all real values of t you will get a value. f(t),t⊂R CT signals are ususally represented by using x(t), having a parentheses and the variable t.
Example: An example would be when you want to know how many people are in a commercial area, which allows us to see how many are actually there.
es: Señales de tiempo continuo
Demographic
Noun or adjective
It is a science that statistically studies human populations; its size, structure, evolution and general characteristics, as well as the specific processes that determine its training, conservation, and disappearance.
Example: An example would be when you have to make measurements whether they are population or chemical products.
es: Demográfico
Discrete-Time Signals
Adjective
A discrete time signal is a signal whose value is taken at discrete measurements. With a discrete time signal there will be time periods of n where you do not have a value. DT signals are represented using the form x[n]. Discrete signals are approximations of CT signals
Example: An example would be to obtain the noise of a piano which generates a signal.
es: Señales de tiempo discreto
Patterns
Noun
You could define patterns as that series of constant variables, identifiable within a larger set of data.
Example: An example would be that of a robot which follows patterns to be able to carry out an activity
es: Patrones
Sampling
Noun
Is the procedure by which certain individuals belonging to a population that is being analyzed are taken
Example: An example would be when you have a small part of a population with which you make an approximate count of how many people live in the place.
es: Muestreo
Signal energy
Nous
The terms signal energy and signal power are used to characterize a signal.
They are not actually measures of energy and power. The definition of signal
energy and power refers to any signal (tx ), including signals that take on
complex values.
Example: An example of an Energy signal is an audio limited in time, since its amplitude tends to 0 when | t | → ∞.
es: Energía de señal
Signals
Noun
Is a function that conveys information about a phenomenon, in electronics and telecommunications, it refers to any time varying voltage, current, or electromagnetic wave that carries information.
Example: An example would be when looking for current in cables with a multimeter which generates a signal on the display.
es: señales
Systems
Noun
It is a group of interacting or interrelated elements that act according to a set of rules to form a unified whole. A system, environment surrounded and influenced, limits, structure and purposes expressed in operations are described.
Example: An example would be when you have an automated system that needs a guidance system that provides the steps to follow.
es: Sistemas
Variations
Noun
It is a dynamic phenomenon and the line voltage can vary according to the time, place, type of load or conditions of the power line.
Example: An example would be when you are taking energy readings that fluctuate, which does not allow you to measure correctly.
