FM signals travel as what changes?
FM signals travel as changes in the frequency of the wave.ANSWER: DEFINITELY not frequency remains the same.The duty cycle changes.It definitely IS the the frequency which changes. It changes at the same rate as the frequency of the modulation.It can be demodulated with a frequency discriminator. If the frequency remained constant and its "duty cycle" changed, the discriminator wouldn't demodulate it.
What determines the pitch or frequency of a string on a violin or guitar?
It changes because it depends if you do it soft or hard that is why it sounds different
What is the difference between amlitude shift key and frequency shift key?
Amplitude shift keying changes the height/power of the transmitted signal without altering the frequency. Frequency shift keying changes the frequency of the transmission without altering the height/power of the transmitted signal. Morse code is an example of amplitude keying where the amplitude is 0 or 100%. RTTY teleprinter uses FSK with two frequencies and the codes that represent text characters are sent with patterns of the two frequencies.
What is frequency Swing?
Frequency swing refers to the variation in frequency of an oscillating signal, often observed in communication systems and electronic circuits. It can occur due to changes in load conditions, modulation techniques, or environmental factors. In wireless communication, frequency swing is essential for maintaining signal integrity and managing interference, especially in frequency-hopping spread spectrum systems. Understanding frequency swing is crucial for optimizing performance in various applications, including radio transmission and signal processing.
Why does an FM receiver not need an AGC feedback path?
An FM receiver does not need an Automatic Gain Control (AGC) feedback path because frequency modulation is less affected by amplitude variations in the received signal. FM demodulation primarily relies on changes in frequency rather than amplitude, allowing the receiver to maintain consistent audio quality regardless of signal strength. Consequently, the need for AGC to manage varying signal amplitudes is minimal, as the demodulated audio remains relatively unaffected by these fluctuations.

What part of a wave changes when the pitch changes?
The frequency of the wave changes when the pitch changes. Pitch is our perception of the frequency of a sound wave, so as the frequency increases, the pitch becomes higher and as the frequency decreases, the pitch becomes lower.
How does the tightening of a musical instrument affect its sound?
Tightening a string changes the fundamental frequency and affects the frequencies of all subsequent harmonics. That's the physics definition. In reality, tightening a string will make its pitch higher (increasing frequency) and keeping strings tightened to where they're supposed to be ensures that it makes the sounds its supposed to make.
How does wavelength change when frequency is constant?
the wavelength changes when the frequency changes if the wavelengths are smaller and thinner then the frequency is high, when the frequency is slow then the wavelengths is larger and wider. if the frequency is constant then the wavelength is a normal size
What would be the observable change in the sound when the frequency changes?
what would be an observable change in sound when the frequency changes
What changes the frequency of an xylophone?
The pitch. The higher the pitch, the higher the frequency.
What would be an observable change in sound when the frequency changes?
An observable change in sound when the frequency changes is a difference in pitch. As the frequency increases, the pitch becomes higher, and as the frequency decreases, the pitch becomes lower. This change in pitch is due to the direct relationship between frequency and pitch in sound waves.
When allele frequency changes, a population is said to no longer be in what state?
When allele frequency changes, a population is said to no longer be in genetic equilibrium.
How does changing the wavelength affects the frequency of a wave?
The wavelength changes inversely with the frequency.
Describe how the frequency of a wave changes as the wavelength changes?
it is directly proportional to frequency so if frequency increases wavelength also increases
When the wavelength changes what changes too?
When the wavelength changes, the frequency changes as well. This is because wavelength and frequency are inversely related in a wave, meaning that as one increases, the other decreases. The speed remains constant.
How did Henry changes in religion affected the people in Britain after they have occurred?
It was affected by people in Britain as they had live there and suffer with the changes.
