What is the domain of a discrete function?
The domain is the possible values that can be input into the function and produce a real number output.
Is the number of foggy days at an airport continuous or discrete?
Either fog occurs on a day, or it does not. Therefore it is a discrete value.
Is education level discrete or continuous?
discrete
Is asthma a discrete or continuous variable?
discrete
Is gender discrete or continuous variation?
discrete
What is the continuous spectrum of a star?
A continous spectrum hasn't discrete gaps between lines.
Is the Hg emission spectrum continuous or discrete?
Hg emission is discrete, that's why you can only see certain (discrete) frequencies, as excited electrons fall from one level to another. A heated light bulb, on the other hand, emits a continuous spectrum from all of its variously vibrating charges.
How did Thomas Edison contribute to economic changes?

What sort of structure does the spectrum of a pulse train have?
A pulse strain has a structure called a frequency comb. This is a spectrum that has a series of discrete and equally spaced elements.
Can The optical spectrum of hydrogen and all other elements consist of a set of discrete lines?
true
What colors on the color spectrum combine to produce gray?
The colors on the color spectrum combined to produce gray are black and white.
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
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.
Is there a mammals that no mamary glands?
Monotremes do not have discrete mamary glands, they do still produce milk.
Why does the sun produce a continuous spectrum but the fluorescent lights produce a line spectrum?
The sun produces a (nearly) continuous spectrum (gaseous elements in the Sun's atmosphere absorb certain frequencies, making it not quite truly continuous) because it's emitting light due mainly to its temperature. This kind of radiation is called "black body" or "cavity" radiation, and it's a continuous spectrum. Fluorescent lights produce light by a phenomenon known as (hold on for the shocking revelation) fluorescence. This kind of radiation is related to transitions between specific electron energy levels, and therefore consists of discrete lines. In old or cheap fluorescent tubes, there might be only a couple of lines. Most modern ones use a mixture of phosphors that emit light at different frequencies, so you might see half a dozen or more lines in the spectrum.
Why is the emission spectrum of hydrogen made of discrete wavelengths rather than a continum of wavelengths?
The emission spectrum of all elements is made of discrete wavelengths. Electrons only exist in particular orbitals. They do not spin willy-nilly around the nucleus. If they receive energy, they jump from one orbital to a higher orbital. When they fall back to a lower orbital, they give off a discrete amount amount of energy. That discrete amount of energy comes as the form of light of a particular wavelength. Look at it as an electron having to be on one or another step instead of a ramp. Instead of continually rolling, it goes one step at a time.
Which type of spectrum can be produced by solid liquid or gas?
The spectrum produced by solid is continuous spectrum. Continuous spectrum is formed by all, solid liquid and gases if the pressure is high. In case of low pressure, gases produce line spectrum.
