Distance between the farthest point of a wave and the equilibrium or mean point
Example: As an example, a pendulum swings through its equilibrium point (straight down), and then swing to a maximum distance away from the center

Analog frequency
noun
In an electrical signal, the voltage, current, or frequency of the signal may be varied to represent the information. Any information may be conveyed by an analog signal; such a signal may be a measured response to changes in a physical variable, such as sound, light, temperature, position, or pressure.
Example: light, temperature, position, or pressure.
es: Frecuencia analógica
Continuous-Time Signals
Noun
Continuous-time signal is the “function of continuous-time variable that has uncountable or infinite set of numbers in its sequence”.
Example: Other examples of discrete-time signals can be found in demographic studies in which various attributes, such as average budget, crime rate, or pounds of fish caught, are tabulated against such discrete variables as family size, total population, or type of fishing vessel, respectively.
es: Señales de tiempo continuo
Discrete-Time Signals
noun
Discrete-time signal is the “function of discrete-time variable that has countable or finite set of numbers in its sequence”. It is a digital representation of continuous-time signal.
Example: A discrete-time signal x[n] may represent a phenomenon for which the independent
variable is inherently discrete. Signals such as demographic data are examples of this.
es: Señal de tiempo discreto
frequency
noun
Frequency is the number of occurrences of a repeating event per unit of time.
Example: "A" note on a violin string vibrates at about 440 Hz (440 vibrations per second).
es: Frecuencia
Power
noun
Power is defined as the amount of energy consumed per unit time. This quantity is useful if the energy of the signal goes to infinity or the signal is “not-squarely-summable”.
Example: Periodic sequences like sinusoid. A sinusoidal signal has finite, non-zero power but infinite energy
es: poder
Signal energy
noun
The definition of signal energy and power refers to any signal (tx ), including signals that take on complex values.
Example: In many, but not all, applications, the signals we consider are directly related to physical quantities capturing power and energy in a physical system.
es: Señal de energia
signals
noun
It is one that presents a discontinuous variation over time and that can only take certain discrete values. Its characteristic shape is widely known: the basic signal is a square wave (pulses) and the representations are made in the time domain.
Example: A speech signal can be represented mathematically by acoustic pressure as a function of time, and a picture can be represented by brightness as a function of two spatial variables. .
es: Señal
Systems
Noun
Is an interconnection of components and devices whereby an input signal is transformed to produce an output signal.
Example: Signals can be classified into analog, time discrete, and digital. The main difference between these signals is whether they are continuous or discrete. in amplitude and time.
es: Sistema
wave
noun
A wave is a solution of a differential wave equation, basically sinusoidal solutions. A signal is a meta level to waves when waves are used to transfer signals.
