Amplitude modulation (AM) is the oldest method of transmitting human voice electronically. In an analog telephone conversation, the voice waves on both sides are modulating the voltage of the ...

AM, or amplitude modulation, was the earliest way of sending voice over radio waves. That makes sense because it is easy to modulate a signal and easy to demodulate it, as well. A carbon ...

Kyushu University researchers have successfully developed a new ferroelectric optical modulator that can exhibited modulation ...

Modulation effects are one of our pedalboard’s essentials. But where do they come from and what do they do? We explore the ...

But for a weekend project, [Vinod.S] took the ultrasonic transmitter and receiver from a distance-meter module and used amplitude modulation to send music ultrasonically from his laptop to a ...
