11 signal terms

acoustic pressure,

Sound pressure or acoustic pressure is the local pressure deviation from the ambient (average or equilibrium) atmospheric pressure

Example: noise

es: presión acústica

Analog frequency

represented by its samples if the sampling frequency is at least equal to double the highest frequency contained in the signal spectrum

Example: radio

es: frecuencia analógica

applied force

s a force that is applied to an object by a person or another object

Example: when we move an object

es: fuerza aplicada

Continuous-amplitude signal

a signal that will have some value at every instant of time.

Example: battery

es: amplitud de señal continua

Continuous-Time Signals

function of continuous-time variable that has uncountable or infinite set of numbers in its sequence”.

Example: The examples for continuous-time signals are sine waves, cosine waves, triangular waves

es: señal continua

digital signal.

digital signal is a continuous-time physical signal, alternating between a discrete number of waveforms, representing a bitstream

Example: tv

es: señal digital

Discrete-amplitude signal

has only a discrete number of possible amplitudes.

Example: computer circuits

es: amplitud de señal discreta

Discrete-Time Signals

it may have been obtained by sampling from a continuous-time signal.

Example: microphone

es: Señales de tiempo discreto

signal

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"

es: señal

Signal energy

refers to any signal ( )tx , including signals that take on complex values.

Example: signal having only one square pulse is energy signal.

es: Energía de señal

systems

a set of principles or procedures according to which something is done; an organized framework or method.

Example: "the public school system"

es: sistemas
