Raman stated that " The line spectrum of the new radiation was first seen on 28 February 1928 . " Thus, combinatorial scattering of light was discovered by Mandelstam and Landsberg a week earlier than by Raman and Krishnan.

This basic " group " was the entire line spectrum on previous long haul carrier systems, such as Types J and K . The first Type A-1 channel banks appeared for use on Type J open wire carrier in 1934.

I think the answer is that in a blazar, the observed emission does not come from the accretion disc ( which would give a broad emission line spectrum, as in a quasar ), but instead comes from the relativistic jet.

The plane wave spectrum is often regarded as being discrete for certain types of periodic gratings, though in reality, the spectra from gratings are continuous as well, since no physical device can have the infinite extent required to produce a true line spectrum.

For example, Type L-4 system used the " Multi-Master Group " system to stack six U600 mastergroups into the L4 line spectrum, while the same hardware was modified to take three of these MMG spectra and stack them into an early L5 line spectrum.

In general, the power spectrum will usually be the sum of two parts : a line spectrum such as in this example, which is not continuous and does not have a density function, and a residue, which is absolutely continuous and does have a density function.

For instance, in one presentation _ " Hubble Space Telescope Imaging of the Proto-Planetary Nebula M2-56, " a title that suffers from the same impenetrability and ennui afflicting a lot of newspaper headlines _ two scientists wrote : " Shock emission dominates the optical line spectrum of the bipolar lobes of M2-56 and shocks probably play an important role in its dynamic evolution ."

He observed that one could not then use any statements about the such things as " the position and period of revolution of the electron . " Rather, to make true progress in understanding the radiation of the simplest case, the radiation of excited hydrogen atoms, one had measurements only of the frequencies and the intensities of the hydrogen bright-line spectrum to work with.
