Molecular assembly has attracted wide attention in chemistry, condensed physics, molecular electronics, and materials sciences. However, it remains a great challenge to perform post-modulation on the ...

In modern wireless communication systems, data transmission is achieved through the collaboration of digital modulation circuits and antennas. Digital baseband signals are first modulated in terms of ...

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 ...
