It refers to how small a signal a receiver can process. All receivers have a "minimum discernable signal" (MDS). Below that level, background noise (static) will be all that you can hear. Your car radio may not process a 1,000 watt signal from a station 1,000 miles away but NASA has receivers that can process 0.1 watt signals from millions of miles away. A lot of it has to do with filtering and the number of amplification stages involved.
What else can I help you with?
What does amplitude measure?
Sound energy travels in waves and is measured in frequency and amplitude
What is sensitivity on modern warfare 2?
It is the speed at which you turn. For example, if your sensitivity is 1 (Low) you will turn slower than if you sensitivity is on 4 (High).
What is the difference between loudness and pitch of sound?
Amplitude versus frequencyLoudness is a function of the sound wave's amplitude of the sound pressure. Aour ear drums are moved by the sound pressure.The greater the amplitude, the greater the volume. Pitch is related to its frequency. The higher the frequency, the higher the pitch.Loudness = amplitude of the sound pressureSoftest soundLoudest soundPitch = frequencyLowest pitchHighest pitch
What is the height of a wavelength?
That is the amplitude.
What is the height of a soundwave which indicates loudness of a sound?
It's the Acoustic Definition of Amplitude.The height of the sound wave is called its amplitude.
What is frequency sensitivity?
the amount of frequency change in the carrier frequency per unit amplitude change in the message signal is the frequency sensitivity this term comes in the frequency moulation
Which factor determine the loudness of a sound?
The loudness of a sound is determined by the amplitude of the sound wave. A higher amplitude corresponds to a louder sound, while a lower amplitude results in a quieter sound. The perceived loudness also depends on the distance from the sound source and the sensitivity of the human ear.
Does the amplitude determine the loudness of a sound?
No, the amplitude of a sound wave determines its intensity, not its perceived loudness. Loudness is subjective and depends on the sensitivity of the human ear to different frequencies at different sound pressure levels.
What is the link between loudness and amplitude?
Loudness is the perception of sound intensity, while amplitude refers to the physical measurement of sound waves. A higher amplitude typically correlates with a louder sound perception, as it represents more energy in the sound wave. However, factors like distance from the sound source and individual hearing sensitivity also influence perceived loudness.
How loud the sound is depends on what?
The loudness of a sound is primarily determined by its intensity, which is related to the amplitude of the sound waves. Other factors that can affect how loud a sound is perceived include the distance from the source of the sound, the medium through which the sound waves travel, and individual differences in hearing sensitivity.
How are the amplitudes of sound waves?
There is not only "one" amplitude. There is an amplitude of particle displacement ξ, or displacement amplitude, an amplitude of sound pressure p or pressure amplitude, an amplitude of sound particle velocity v, or particle velocity amplitude, an amplitude of pressure gradient Δ p, or pressure gradient amplitude. If the "sound" inceases, the "amplitude" also increases.
A sound waves amplitude corresponds to the sounds what?
Usually, people are asking as if there is just "the" amplitude in sound waves in air. The loudness perception of a sound is determined by the amplitude of the sound waves − the higher the amplitude, the louder the sound. Which amplitude of sound (sound amplitude) do you mean? There are: amplitude of particle displacement ξ, or displacement amplitude amplitude of sound pressure p or pressure amplitude amplitude of sound particle velocity v, or particle velocity amplitude amplitude of pressure gradient Δ p, or pressure gradient amplitude. Furthermore, think of the amplitude of the oscillation of a string. The maximum magnitude of the deflection of a wave is called amplitude. Look at link: "What is an amplitude?"
What does loudness describe?
Loudness describes the perceived intensity or volume of a sound. It is subjective and influenced by factors such as the amplitude of the sound wave and the sensitivity of the human ear. Loudness is typically measured in decibels (dB).
What is maximum displacement of the wave from equilibrium called?
The term for maximum displacement is the amplitude of the wave.
On what factor the loudness of sound depend upon?
The loudness of a sound depends on the amplitude of the sound wave. A higher amplitude corresponds to a louder sound. The human perception of loudness also depends on the frequency of the sound wave and the sensitivity of the human ear.
How do you determine the ratio of an amplitude?
Amplitude ratio to dB conversion:For amplitude of waves like voltage, current and sound pressure level:GdB = 20 log10(A2 / A1)A2 is the amplitude level.A1 is the referenced amplitude level.GdB is the amplitude ratio or gain in dB.dB to amplitude ratio conversion:A2 = A1 · 10(GdB / 20)A2 is the amplitude level.A1 is the referenced amplitude level.GdB is the amplitude ratio or gain in dB.
When signal amplitude is equal to carrier amplitude then modulation index is?
