The circuit was designed to be able to obtain signals via amplitude modulation where the sensitivity and selectivity is fairly good. Amplitude Modulation AM – a method of emphasizing data on an ...

This study presents a highly efficient graphene-based electro-optical phase and amplitude modulator operating at 1550 nm, specifically designed for the TE fundamental mode. A phase difference of π is ...

Researchers at Skoltech have developed an ultra-compact electro-optic modulator based on silicon photonics and plasmonics that enables high-efficiency optical signal control within a small device ...

We recently saw how certain audio power amplifiers can be used as oscillators. This Design Idea shows how those same parts can be used for simple amplitude modulation, which is trickier than it might ...

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 ...
