pulse modulation

  1. Modulation of a carrier signal by a train of pulses, as in pulsed radar.

  2. Use of a series of pulses modulated to carry information. The modulation may involve changes of pulse amplitude, position, phase, or duration.

  3. Modulation of the waveform characteristics within an individual pulse during the duration of the pulse, as in pulse compression.
