Modulation is the act of translating some low-frequency or baseband signal (voice, music, and data) to a higher frequency. Why do we modulate signals? There are at least two reasons: to allow the ...

Excellent electromagnetic wave absorption is realized via the synergistic design of a dual-phase heterostructure, defect engineering, and magnetic loss modulation. The spinel/rock salt interface ...

A team of researchers from the Center for Research and Innovation in Metamaterials at the University of Exeter and the Laser Processing Group at the Institute of Optics have presented in the journal ...

This is Part 1 of a three-part series. As modern wireless communications systems (mainly superheterodyne radio transceivers) are now required to deliver higher performance than ever before, they’re ...

Notches are specific frequencies attenuated or boosted by the modulation effect. In a phaser effect, for example, notches are created by the phase cancellations that occur when two signals combine. By ...

This is Part 2 of a three-part series. As discussed in Part 1 and recapped here, modern wireless communications systems (mainly superheterodyne radio transceivers) are now required to deliver higher ...
