When we think about signals and systems, we often do so with an emphasis on creating and transmitting signals with specific characteristics. That is, we want the signal to have some desired amplitude, ...

Conventional techniques may not be sufficient, but a new approach to implementing nonlinear algorithms may accomplish the goal. Roy Batruni, CEO, Optichron Nonlinear signal distortion is widespread ...

The transmission standard for 4K8K satellite broadcasting ISDB-S3 has adopted 16APSK and 32APSK as new modulation schemes. 16APSK has been used for the 4K8K UHDTV broadcasting service in Japan since ...

CONVENTIONAL low-frequency delay lines, built from capacitors and iron-cored inductors, show both linear and non-linear distortion. The linear distortion gives rise to dispersion, since the time delay ...

Digital predistortion is an approach to amplifier linearization that permits the efficiency of the multi-carrier amplifier to be dramatically increased. The principle of predistortion is intrinsically ...

Measurements of the non-linear distortion products generated by a system, such as a loudspeaker, which has more than one degree of freedom must be made as a continuous function of frequency it a true ...

Measurements of the non-linear distortion products generated by a system, such as a loudspeaker, which has more than one degree of freedom must be made as a continuous function of frequency it a true ...

FOR lack of any proved method of objective assessment the degree of non-linear distortion permissible in transmission systems which handle high-quality speech and music programmes has been decided, up ...

An investigation into these aspects of distortion measurement is described with the object of showing the unreliability of the present methods of specifying ...
