A glossary of the most relevant words or concepts that I consider will be made.
Analog frequency
adverb
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: is the loudspeaker, which is used to amplify the sound so that it is heard by a large audience.

Continuous-amplitude
adverb
A signal of continuous amplitude and time is known as a continuous-time signal or an analog signal. This (a signal) will have some value at every instant of time. The electrical signals derived in proportion with the physical quantities such as temperature, pressure, sound etc. are generally continuous signals
Example: examples of continuous signals are sine wave, cosine wave, triangle wave

continuous-time signal
adverb
that is defined for all time t contained in some interval on the real line. For historical reasons, CT signals are often called analog signals.
Example: For example, if you were monitoring the temperature of a room, you would be able to take a measured value of temperature at any time.

digital signal.
noun
The digital signal is a type of signal in which each sign that encodes its content can be analyzed in terms of some quantities that represent discrete values, instead of values within a certain range.
Example: We find them in communication buses, in clock signals of electronic devices, PWM signals to modulate power in an element, among others

Discrete-time signal
adverb
A discrete signal or discrete-time signal is a time series consisting of a sequence of quantities. Unlike a continuous-time signal, a discrete-time signal is not a function of a continuous argument; however, it may have been obtained by sampling from a continuous-time signal.
Example: For example, if you were monitoring the temperature of a room, you would be able to take a measured value of temperature at any time.

electrical signal
noun
An electrical signal is a type of signal generated by some electromagnetic phenomenon. These signals can be of two types: analog, if they vary continuously over time, or digital if they vary discretely. An electrical signal can be defined in two ways:
Example: The microphone converts sound waves into a variable voltage that can be measured between the microphone wires.

Resistance
noun
Resistance is a measure of the opposition to current flow in an electrical circuit.
Example: Current must struggle to flow through the small coils of a toaster, enough to generate heat that browns bread. Old-style incandescent light bulbs force current to flow through filaments so thin that light is generated.

Signal energy
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: a signal having only one square pulse is energy signal
en: Energía de señal
signals
noun
A signal can also be the variation of an electric current, or another physical quantity that is used to transmit information.
Example: in telephony there are different signals, which consist of a continuous or intermittent tone, in a characteristic frequency, which allows the user to know what situation the call is in.

systems
noun
a group of related hardware units or programs or both, especially when dedicated to a single application.
Example: the variations over time of the applied force f and the resulting automobile velocity v are signals.
en: sistemas
Voltage
noun
The electrical voltage or potential difference is a physical quantity that quantifies the electrical potential difference between two points. It can also be defined as the work per unit charge exerted by the electric field on a charged particle to move it between two determined positions.
Example: Energy that reaches your house and you can turn on a light bulb
