What is the spectrum of a signal?
2Fb/M
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.
Define energy and power signal?
Here Energy signals are limited but power signals can exist to infinite distance. Non periodic signals are energy signals while power signals are periodic.
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

Is the bandwidth equal in each cycle of a periodic signal?
Yes, If you perform a windowed Fourier Transform of a truly periodic signal using a window function exactly one cycle wide the results will be exactly the same signal frequency spectrum, regardless of where on the signal you placed the window function. But you should also realize the results will also be the same signal frequency spectrum using a window function of any width that is an integer multiple of one cycle (greater than zero), or even without any window function at all. This signal frequency spectrum contains all the information needed to determine what is commonly called the bandwidth of the signal (and that spectrum often contains frequencies outside that bandwidth, but usually only at very low amplitudes so that their loss in filters, etc. is not generally considered significant).
What is periodic signal?
A periodic signal has two major characteristics: frequency and amplitude. Frequency is the number of times the periodic signal occurs in a set time, and the amplitude refers to how strong the signal is.
What is the difference between periodic and aperiodic signals?
A signal which repeats itself after a specific interval of time is called periodic signal. A signal which does not repeat itself after a specific interval of time is called aperiodic signal.A signals that repeats its pattern over a period is called periodic signal,A signal that does not repeats its pattern over a period is called aperiodic signal or non periodic.Both the Analog and Digital can be periodic or aperiodic. but in data communication periodic analog sigals and aperiodic digital signals are used.
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.
Why we use periodic analog and non periodic digital signal in communication?
In data communication computer use periodic analog signal because it Need Less Bandwidth. So, by using Periodic Analog Signals it is easy to select the Medium through Which data is travelled otherwise it is Much Difficult (aprox. Impossible ) .
What is the label on the y-axis of a mass spectrum?
"signal intensity" is the y- axis of a mass spectrum.
What are the characteristics of a periodical?
A periodic signal has two major characteristics: frequency and amplitude. Frequency is the number of times the periodic signal occurs in a set time, and the amplitude refers to how strong the signal is.
Is the frequency domain plot of an alarm system discreet or contineous?
discrete because the signal of an alarm is periodic.
Why mostly periodic analog and non-periodic digital signal used in communication?
yes and no
Need of fft?
FT is needed for spectrum analysis, FFT is fast FT meaning it is used to obtain spectrum of a signal quickly, the FFT algorithm inherently is fast algorithm than the conventional FT algorithm
