The average textbook definition of modulation reads: modulation is a process in which the frequency, phase or amplitude of a carrier wave varies in step with the instantaneous value of the modulating ...

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 ...

LASER COMPONENTS would like to introduce its phase modulator especially designed to operate in the 1000nm wavelength band. The NIR-MPX series use a proton exchanged based waveguide process that ...

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 ...

Kyushu University researchers have successfully developed an ultra-high-speed optical modulator that can operate at more than ...
