Amplitude
noun
is the distance between the center line of the function and the top or bottom of the function, and the period is the distance between two peaks of the graph, or the distance it takes for the entire graph to repeat.
Example: the amplitude of alpha rhythm

Analog frequency
conjunction
is any continuous signal for which the time-varying feature of the signal is a representation of some other time-varying quantity, i.e., analogous to another time-varying signal.
Example: The analog frequency should satisfy the condition in Equation to avoid any discontinuity in DFT.

Continuous-Time Signals
conjunction
is a function, s(t), that is defined for all time t contained in some interval on the real line.
Example: A signal of continuous amplitude and time is known as a continuous-time signal or an analog signal.

Digital signal
conjunction
is a signal that is being used to represent data as a sequence of discrete values; at any given time it can only take on, at most, one of a finite number of values.
Example: Simple digital signals represent information in discrete bands of analog levels.

Discrete-Time Signals
conjunction
is a time series consisting of a sequence of quantities.
Example: Most discrete-time signals come from sampling continuous-time signals to get them into a digitised form that can be processed by digital computers.

Fluctuations
noun
an irregular rising and falling in number or amount; a variation
Example: fluctuations in the yearly values could be caused by a variety of factors
en: Fluctuaciones
Independent variable
noun
a variable (often denoted by x ) whose variation does not depend on that of another.
Example: On the other hand, discrete-time signals are defined only at
discrete times, and consequently, for these signals, the independent variable takes on only
a discrete set of values.

Signal energy
noun
The definition of signal energy and power refers to any signal ( )tx , including signals that take on complex values.
Example: Signal Energy has thousands of megawatts of renewable energy projects complete, in operation, and performing above expectations.

Signals
verb
is a gesture, action, or sound that is used to convey information or instructions, typically by prearrangement between the parties concerned
Example: The firing of the gun was the signal for a chain of beacons to be lit
en: Señales
Speech signal
conjunction
is a slowly timed varying signal (it is called quasi-stationary)
Example: A speech signal as a function of time and atmospheric pressure
as a function of altitude are examples of continuous-time signals.

Systems
noun
is a set of things working together as parts of a mechanism or an interconnecting network.
Example: The systems are reliable in operation, durable and easy to install.
