Modulation is a technique in which message signal is transmitted to the receiver with the help of carrier signal. Here in modulation, we combine both carrier signal and message signal. In this post, ...

Doing more with less in electronics often means improving power density. One of the new areas garnering attention involves applying a variety of advanced modulation techniques, including PWM and space ...

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 ...

Active metadevices integrated with semiconductors. (a) Hybrid silicon-metallic resonators for all-optical ultrafast active metamaterials. (b) Broadband metamaterial frequency switch with femtosecond ...
