Why does the ITU-R only regulate lower frequencies up to some hundred GHz and not higher frequencies in the THz range?
Because of their higher reach. And thus, military applications and others should be free to use them regardless of the country or region where they are transmitted. Higher frequencies have a much lower reach, since their wavelength is lower, and so there's sense in regulating them.
Besides, lower frequencies implies lower data transmission rates, and hence its lower importance as well, I'd say!
What else can I help you with?
In twisted-pair wire how does the twist ratio affect transmission?
(1) the higher the twist, the higher the throughput (2) The higher the twist, the the lower the crosstalk
Why noise immmunity is more in integrator than differentiator?
noise is a ac signal(high frequency range), as LPF allows only lower frequencies integrator is has more noise immunity than differentiator
What are the advantages and disadvantages of mid range computer?
The advantage is lower purchase price. The disadvantage is that the computer has lower or mid-range specifications compared to a higher-end computer. A mid range is suitable for normal home computer use. A higher-specification is better for gaming.
Why the frequency of aeroplanes is 400 Hz?
Higher the fequency , higher the speed. Similarly,freq is inversely proportional to the the flux , higher the freq lower the flux requirement hence lower the winding req. which will reduce the weight ( this is necessary req. in operation of Aeroplane) of the winding The higher frequency allows a lighter transformer. Doubling the frequency allows the transformer's iron core to be half the weight. So 400 Hz allows light transformers (and motors) to be used.
What is the difference between frequency and pitch?
The human ear is capable of detecting sound at frequencies between about 20 and 20,000 Hz. Within this frequency range, however, the response of the ear is not uniform. The ear is most sensitive to frequencies between 200 and 4000 Hz, and its response decreases toward both higher and lower frequencies. There are wide variations in the frequency response of individuals. Some people cannot hear sounds above 8000 Hz, whereas a few people can hear sounds above 20,000 Hz. Furthermore, the hearing of most people deteriorates with age. The sensation of pitch is related to the frequency of the sound. The pitch increases with frequency. Thus, the frequency of middle C is 256 Hz, and the frequency of the A above is 440 Hz. There is, however, no simple mathematical relationship between pitch and frequency. frequency causes the different types of pitch

How are sound do classified into different pitches?
Sounds are classified into different pitches based on their frequency. The pitch of a sound refers to how high or low the sound is perceived, with higher frequencies corresponding to higher pitches and lower frequencies corresponding to lower pitches. In general, sounds with higher frequencies are perceived as higher pitches, and sounds with lower frequencies are perceived as lower pitches.
How are sounds classified into different pitches?
Sounds are classified into different pitches based on their frequency. High-pitched sounds have higher frequencies, while low-pitched sounds have lower frequencies. This frequency is measured in hertz (Hz), with higher frequencies corresponding to higher pitch and lower frequencies corresponding to lower pitch.
What the frequencies of sonar are?
Sonar frequencies typically range from around 20 kHz to several hundred kHz. Lower frequencies can travel long distances in water, but higher frequencies provide better resolution for detailed imaging. The choice of frequency depends on the specific application and environmental conditions.
How do sounds get higher or lower?
Sounds get higher or lower depending on the frequency of the sound waves. Higher frequencies produce higher pitches, while lower frequencies produce lower pitches. This means that a faster vibration of the sound wave will result in a higher pitched sound, and a slower vibration will result in a lower pitched sound.
Is it better to have high Wavelengths or low Wavelengths?
It depends on the context. In terms of light, shorter wavelengths (higher frequencies) have more energy, while longer wavelengths (lower frequencies) have lower energy. In terms of sound, shorter wavelengths (higher frequencies) are perceived as higher pitched, while longer wavelengths (lower frequencies) are perceived as lower pitched.
Why do we use high frequency waves as carrier waves?
The use of high frequencies for carrier waves in communications permits a higher rate of information transfer than could be accomplished with lower frequencies. The higher frequencies have the potential for higher "data density" or "information density" than lower frequencies.
The frequency of a sound wave determines?
The frequency of a sound wave determines the pitch of the sound, with higher frequencies corresponding to higher pitches and lower frequencies corresponding to lower pitches.
How is the pitch of sound related to frequency?
Human auditory range is about 20 hz to 20khz, but can vary slightly from person to person. Lower frequencies are lower in pitch and higher frequencies are higher in pitch.
How does the frequency of a sound wave affect its pitch?
The frequency of a sound wave directly affects its pitch. Higher frequencies result in higher pitches, while lower frequencies result in lower pitches.
What is the relationship between tone and frequency in sound waves?
The tone of a sound wave is determined by its frequency. Higher frequencies produce higher tones, while lower frequencies produce lower tones.
What are the guitar note frequencies and how do they affect the sound produced by a guitar?
Guitar note frequencies refer to the vibrations produced by plucking a guitar string, measured in Hertz (Hz). Higher frequencies create higher-pitched notes, while lower frequencies produce lower-pitched notes. The frequency of a guitar note affects its pitch and tone, with higher frequencies sounding brighter and lower frequencies sounding deeper. Different frequencies can also create harmonics and overtones, adding complexity to the sound of the guitar.
