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 ...

O. Shimbo, and W. L. Cook, in the COMSAT Technical Review. 3 Shimbo et al. provide a computational method to estimate the undesired interference caused by intermodulation products of angle-modulated ...

Long wires or distant wireless communications always garble the transmission. How can an engineer cure that distortion? Turns out, a lot of math and a little experience can work wonders. This author ...

As we’ve traced our no-nonsense path through the world of Hi-Fi audio, we’ve started with the listener, understood the limitations of the human ear, and thence proceeded to the loudspeaker. We’ve ...

When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. Just like NTSC transmitters had to deal with linear and nonlinear distortions, so do today’s DTV ...

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 ...

Optical fibre communication has enabled the exponential growth in communication capacity of the information era. The theoretical capacity upper bound of a linear communication link is set by the ...

Two things have been overlooked with phasing amplitude modulation. One is the importance of pulse modulation; the other is that logic gates can be used for analog signal processing. Both of these ...

Achieving unidirectional signal flow—where information travels in only one direction—is vital for next-generation communication systems. Micromechanical devices leveraging parity-time (PT) symmetry ...
