Varying the voltage of a carrier or a direct current in order to transmit analog or digital data. Amplitude modulation (AM) is the oldest method of transmitting human voice electronically. In an ...

Modulation is fundamental to electronic communications. The modulating signal might be analog in nature (voice or music) or digital bit streams. Most modern communication systems are digital, using ...

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 ...

Modern society is definitely more mobile than it was several decades ago. Accompanying the increased mobility is a corresponding craving for greater quantities of information. The increased demand has ...

This study proposes a novel method to accurately estimate modulation amplitude and determine spatial resolution in BOCDR without additional devices. Brillouin scattering is the phenomenon of the ...

As a next-generation optical archive storage device for 8K video, we have been researching and developing holographic memory. Recent studies have focused on multi-level code instead of binary code to ...

EKSMA Optics offers a wide range of high voltage drivers tailored for specific laser applications, including Q-switching, pulse injection, cavity dumping, and CW beam chopping. We have just introduced ...

Modulation is the process of varying a higher frequency carrier wave to transmit information. Though it is theoretically possible to transmit baseband signals (or information) without modulating it, ...
