What is tone and pitch?
Loudness, pitch and timbre are approximately the correlates of signal amplitude, frequency and frequency spectrum, respectively.
How can pitch an volume change?
Loudness (volume), pitch and timbre are approximately the correlates of signal amplitude, frequency and frequency spectrum, respectively.
What Signal is transmitted by frequencies in the 300- GHz to 300000-GHz range which is just above the top of the wireless spectrum as it is defined by the FCC?
Infrared
What is difference between pitch and volume?
Volume (loudness), pitch and timbre are approximately the correlates of signal amplitude, frequency and frequency spectrum, respectively.
What is an audio spectrum analyzer?
Audio frequency spectrum is measured in Hertz's (Hz) and tells the range of audible audio. The human hearing range is usually 20-20000Hz, but especially the audibility of the top end of the spectrum declines with age. Most software analyzers measure between 0 Hz and 16000-24000kHz
What is relationship between signal spectrum and bandwidth?
Signal Bandwidth is the Bandwidth of particular frequency at which signal is transmitted and Bandwidth of spectrum which can able two show number of signal between Intrest of frequency.
What is the label on the y-axis of a mass spectrum?
"signal intensity" is the y- axis of a mass spectrum.
What defines the bandwith of a composite signal?
The width of the frequency spectrum
What is essential bandwidth of FM signal?
"Essential bandwidth" is the portion of the signal spectrum that encompasses most of the energy of the original signal in the frequency domain.
Why is the frequency spectrum of a discrete signal repetitions of the spectrum of the analog signal?
The analog signal is converted to discrete signal. Even after the conversion, the frequency of the actual signal still remains the same. If the frequency of the discrete signal is different from the analog signal, the reconstructed signal would be different again. This is not what we expect. So base spectrum for similar signals have same frequencies, whether they are discrete or analog. Why do the repetitions occur? The original analog signal is multiplied with a dirac pattern. The base frequency is then shifted to the places, where diracs are available. So long the diracs keep repeating, the base frequency do repeats. Hope you are convinced with my answer
What is The use of multiple frequencies to transmit a signal?
spread-spectrum technology
What is meant by a low pass signal?
A low pass signal whose bandwidth is much smaller than its center frequency, such as an AM signal. It is a a signal with its spectrum concentrated around zero frequency.
Is sawtooth signal analog?
Yes. A signal of plateaus shows quantized or discrete levels of one or the other voltage; only 2 states. A sawtooth signal has a spectrum of states and has many more than 2 discrete states and is thereby analog. A sine wave is also an example of an analog signal - a spectrum of intensity.
What tool would you use to assess the quality of a wireless signal?
spectrum analyzer
WHAT ARE parametric and non parametric methods of power spectrum estimation in digital signal processing?
Parametric and Non Parmetric are the of power spectrum estimation of random signal. in nonparmetric method there no assumtion about how the data is generated of which power is to be calculate. sanket lichade
What is bandpass signal?
A bandpass signal, xc(t), is a signal whose one-sided energy spectrum is both: 1) centered at a non-zero frequency, fC, and 2) does not extend in frequency to zero (DC). The two sided transmission bandwidth of a signal is typically denoted by BT Hertz so that the one-sided spectrum of the bandpass signal is zero except in [fC − BT /2,fC + BT /2]. This implies that a bandpass signal satisfies the following constraint: BT /2 < fC. Fig. 1.1 shows a typical bandpass spectrum. Since a bandpass signal, xc(t), is a physically realizable signal it is real valued and consequently the energy spectrum will always be symmetric around f = 0. The relative sizes of BT and fC are not important, only that the spectrum takes negligible values around DC. In telephone modem communications this region of negligible spectral values is only about 300Hz while in satellite communications it can be many Gigahertz.
Difference between spectrum analyzer and distortion analyzer?
The spectrum analyzer is used to do distortion analysis to the signal. Due to the fact that we don't have a pure generated signal. In reality, there must be some distortion. The distortion analysis is important in the communication field as well as in electronics.
