But for a weekend project, [Vinod.S] took the ultrasonic transmitter and receiver from a distance-meter module and used amplitude modulation ... modulated sounds waves. The transmitter and ...

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 ...

He designed a transmitter to send and a receiver to detect radio waves. By the end of the century Marconi had managed to send signals over several miles with no wires, and the idea was taking hold ...

AM (Amplitude Modulation) is a method of broadcasting radio and covers both Medium Wave (MW) and Long Wave (LW). Most AM radios have in-built aerials so the location of the radio is often the most ...

Table 2 shows the transmission parameters for the 2-transmitter SC-FDE method for performing 400-Mbps-class mobile wireless transmission using millimeter waves in the 42-GHz band. The modulation ...

In this context, transmitters—which send information via radio waves ... adopted transmitter type, digital polar transmitters ...
