Pulse-width modulation in sigma-delta modulators
Proceedings of 2010 IEEE International Symposium on Circuits and Systems, 2010Time-encoding machines map analog or multi-bit digital signals to a binary stream. The information contained in the input signal is preserved by the high resolution achieved in the time domain. Pulse-Width Modulators (PWMs) rely on a similar operation principle.

Affordable, short pulse Marx modulator
2013 19th IEEE Pulsed Power Conference (PPC), 2013High energy, short-pulse modulators are being re-examined for the Compact Linear Collider (CLIC) and numerous X-Band accelerator designs. At the very high voltages required for these systems, all of the existing designs are based on pulse transformers, which significantly limit their performance and efficiency.

Soliton pulse position modulation
IEE Proceedings J Optoelectronics, 1993The phenomenon of a train of optical fibre solitons, modulated in some way by impressed disturbances, is increasingly being identified as a new type of dynamical system, with interesting dynamical behaviour which can be studied both experimentally and mathematically.

Realtime Aspects of Pulse-to-Pulse Modulation
1992The pulse-to-pulse modulation of the SIS-ESR control system is described. Fast response to operator interaction and to changes in process conditions is emphasized as well as the essential part played by the timing system in pulse-to-pulse modulation. The benefits of pulse-to-pulse modulation in acceleration operating have been described as early as ’77

Proceedings of the IRE, 1953
Following a review of the principles of pulsed transmission of information, the method of pulse code modulation (p.c.m.) is discussed. Two different experimental systems for performing this function are described.

Bell System Technical Journal, 1955
The impetus for the development of magnetic pulse modulators for radar gear stems from the extreme reliability possible for magnetic devices. Descriptions of magnetic modulators developed for this purpose are given. Mathematical treatments of both the ac and dc charged series type magnetic modulators add to the understanding of core resetting in the ac

Transactions of the American Institute of Electrical Engineers, 1947
A radically new modulation technique for multichannel telephony has been developed which involves the conversion of speech waves into coded pulses. An 8-channel system employing pulse code modulation (PCM) and embodying these principles was produced. The method appears to have exceptional possibilities from the standpoint of freedom from interference ...

A transistorized pulse code modulator
Transactions of the I.R.E. Professional Group on Electronic Computers, 1954A pulse code modulator is described in which transistors are the only active circuit components. The functions of quantizing and encoding the signal are performed entirely by semiconductor diodes, using transistor amplifiers where necessary to increase the signal level.

The term pulse code modulation (PCM) refers to the use of a specific set of rules for transforming a waveform into a stream of digits, and vice versa. To clarify the concept, however, the first point to be made is that PCM is coding, but it is not necessarily the modulation of the carrier.
