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 ...

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 ...

Fundamental to all wireless communications is modulation, the process of impressing the data to be transmitted on the radio carrier. Most wireless transmissions today are digital, and with the limited ...

We all love our wireless devices. We want more features, higher data rates, and improved range. These demands, in turn, require advanced digital protocols. Meanwhile, the number of signal sources is ...

Modern oscilloscopes capture, view, measure, and analyze complex RF signals in the time, frequency, and modulation domains. Time-domain analysis, the original oscilloscope function, allows users to ...

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 ...

Jenoptik is one of the few companies in the world to address the market for pulse modulation of high and low power lasers. The Digital Imaging business unit presents at Photonics West their highly ...

Magnacom emerged from stealth mode claiming it has a new twist on digital modulation technology that provides big gains for any wired or wireless network. The company will license its technology on ...
