That is to say, metaphysical thinking offers more opportunities to develop new types of modulations that may in fact facilitate rather than inhibit processes of individuation, of democratic group-formation, or of collective engagement.
Deleuze's description of modulation can clearly be understood in terms of changing labour conditions: under Taylorism, workers worked according to strict codes and followed well-defined instructions in the factory; towards the 1980s, a new mode of control began to appear, which the French sociologist Philippe zarifian calls a 'control by modulation', which 'gave the worker a certain freedom to manage his time, displacement and a good number of his actions'.
At present more than nine different features can be used to recognize different modulations.
ABSTRACT: Modulation classification plays a key role in demodulation of the received signal for extracting the required information.
For the 2nd bandgap, modulations occur first at the gap center and gradually blue-shift to bandedges; for N close to integral values small right "bandage islands" appear.
Gap center modulations were only present at low RI contrast TvPCs.
The generators can be disconnected from their normal modulators to drive other modulators, such as scan or pulse, and can be synchronized for complex modulation.
The key to this complex modulation function is the ability to download custom waveforms to the modulation generators, which are DDS.
Operators are looking at adaptive modulation microwave radios as one of the ways to address the need for increased capacity.

The discrete mode modulator produces a spectrum that is centered on the carrier frequency and is rich in odd harmonics of the modulation frequency.
These unique capabilities extend the capture and analysis power of Agilent's logic analyzer products by providing advanced tools for making modulation quality measurements on a variety of digital communication signals.
