How do the frequencies of waves with different amplitudes compare?
There's no dependence or connection between a wave's amplitude and its frequency.
Give the difference between LPF and HPF?
LPF is a low pass LTI filter which passes the low frequency signals and reduce the amplitude of the signals with frequencies higher than the cutoff frequency. HPF is high pass LTI filter which passes the high frequencies and reduce the amplitude of the frequencies lower than filter's cutoff frequency.
How does increased frequancy affect amplitude?
Increasing frequency does not directly affect amplitude in a linear way. However, in some systems, particularly mechanical or electrical ones, resonance may occur at specific frequencies, causing an increase in amplitude. This phenomenon is due to the system being driven at its natural frequency, resulting in larger oscillations.
Where should I go for medical transcription training?
this value is 1 percent of the unmodulated carrier amplitude. We may thus define the transmission bandwidth of an FM wave as the separation between the two frequencies beyond which none of the side frequencies is greater than 1 percent of the carrier amplitude
What is the effect of frequency on amplitude?
The relationship between frequency and amplitude depends on the system being analyzed. In some systems, increasing frequency may result in an increase in amplitude (resonance), while in others it may decrease. Generally, higher frequencies can lead to higher amplitudes in resonant systems, while non-resonant systems may have a more complex relationship between frequency and amplitude.
The loudness of a sound is a reflection of its?
The "loudness" with which you perceive a sound is determined by -- the amplitude of the sound as it leaves the source -- the distance between you and the source -- obstacles or absorptive media in the path between the source and your ear -- reflective surfaces near the path, leading to multipath interference, constructive or destructive at the frequencies that comprise the sound -- the relative amplitude response of your ear at the frequencies that comprise the sound.
What is frequency range of amplitude moulation radio?
Any radio signal, regardless of its frequency, can be amplitude-modulated in order to add information to it. In the US, commercial broadcast AM radio stations operate on carrier frequencies between 540 KHz and 1.7 MHz.
Relationship between period and amplitude of a wave?
The amplitude of a sound is not related to its frequency (wavelength).There might appear to be a connection if the listener's hearing is more or less sensitive to certain frequencies. For example, as a sound with constant amplitude rises in frequency toward the upper limit of the listener's hearing range, it will be perceived as if its amplitude (loudness) is dropping, although that sensation is in the ear of the beholder and not a property of the sound itself.
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.
Two sound waves of the same frequency can interfere with each other but two sound waves must have different frequencies in order to make beats. Why?
When two sound waves of the same frequency interfere, they can either create constructive interference (amplitude adds up) or destructive interference (amplitude cancels out), leading to changes in loudness. However, for beats to occur, there must be a slight difference in frequency to create interference patterns that result in the perception of amplitude modulation. This difference in frequency introduces variation in the interference pattern, causing the beats to be heard.
What is the difference between the standard amplitude modulation linear addition and multiplication of signals?
In modulation u r sending two signals but their frequencies are sum or difference of carrier frequency and signal frequency.In addition u send two signals at two different frequencies so more interference.
What does a resonance graph illustrate and how does it help in understanding the behavior of a system?
A resonance graph illustrates the relationship between the frequency of a system and its amplitude of vibration. It helps in understanding the behavior of a system by showing at which frequencies the system vibrates most strongly, allowing for the identification of resonant frequencies and potential issues that may arise from them.
