  • n. Sound modulated; melody.
  • n. A change of key, whether transient, or until the music becomes established in the new key; a shifting of the tonality of a piece, so that the harmonies all center upon a new keynote or tonic; the art of transition out of the original key into one nearly related, and so on, it may be, by successive changes, into a key quite remote. There are also sudden and unprepared modulations.
  • n. The alteration of hte amplitude, intensity, frequency, or phase (of the carrier wave of a radio signal) at intervals, so as to represent information to be transmitted.

  • I rather imagine that the neglect and perversion or repression of this modulation is due very largely to the general neglect of the proper development of the imagination and emotion in our whole educational system.

    Public Speaking

  • Another modulation is that of tone colour, the sign of imagination and emotion.

  • (One can also refine the above ansatz in a number of ways, for instance by also introducing a frequency modulation, which is particularly important in models such as the mass-critical NLS which admit a frequency modulation symmetry, but for simplicity we will not consider this more complicated situation here.)

  • The solution to this was, in part, a switch from the early, cheap CAP (carrierless amplitude / phase) modulation, which treated the entire swath of spectrum allotted to DSL as one big modem signal, more or less, to DMT (discrete multi-tone) modulation, which is quite close to OFDM (orthogonal frequency division multiplexing) in some of its particulars.
