¿Cómo es la onda percibida por un osciloscopio cuando hablamos de sonido? ¿Qué parámetros podemos observar en ella?
frozen [14]

Answer:

Las ondas de sonido, que es una onda longitudinal, son producidas por la vibración de un objeto de tal manera que (la onda de sonido requiere un medio de viaje, líquido sólido o gas) la dirección del sonido es la misma que la dirección de la vibración y como la el ancho de la vibración (hacia adelante y hacia atrás) aumenta, la amplitud de la vibración aumenta y el sonido es más fuerte

Un micrófono conectado al osciloscopio recoge el medio de aire vibrante de la onda de sonido de la energía de la onda de sonido y lo convierte (produce) señales eléctricas y electrónicas. El osciloscopio, que está diseñado para mostrar señales electrónicas, muestra las señales electrónicas transmitidas por el micrófono en la pantalla con los mismos valores de amplitud y frecuencia que el volumen y el tono de la onda de sonido, respectivamente.

Las características observables son;

1) El volumen o el volumen de la onda de sonido que se muestra como la amplitud) en el cátodo, con una amplitud más alta que representa un sonido más fuerte

2) El tono de la onda de sonido se muestra como el espaciado de onda en el osciloscopio, el sonido de tono más alto se muestra por las ondas que se acercan en la pantalla

What should you do when an error message pops up on the screen?
Shtirlitz [24]
The best thing to do when an error message appears when it is not supposed to, as in if you are blocked by an administrator and it appears then its supposed to, it is best to contact someone who can investigate whether or not something is happening to your computer. That could be a parent, if they are good with computers, or just tech support at a store, provided they also know computers. Most of the time your computer just makes a mistake so nothing to worry about, but make sure to have it checked just to be sure.
