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 ...

[GreatScott] does exactly this in the video after the break, building both a transmitter and receiver. At the most basic level, AM radio works by generating a carrier wave with an oscillator ...

Voyager 1 is now using a radio transmitter it hasn’t relied on since 1981 to stay in contact with its team on Earth while engineers work to understand what went wrong. As the spacecraft ...

Then enter your address details and the tool will find your local transmitters and check for problems in your area. Please note the tool provides info for terrestrial TV and radio transmitters only.

Fiber optic transmitters convert electrical signals into optical signals and then inject these optical signals into light-conducting cable. They use light emitting diodes (LED) or laser diodes as ...

Pressure transmitters used in the process industries are very durable and reliable instruments. Even so, they still require periodic maintenance and calibration to ensure optimal performance. This is ...

Our picks for best headphone adapters, best Bluetooth audio receivers for home stereos, and best Bluetooth transmitters are listed below. These days, most mainstream audio electronics have ...

Because most controllers and displays use input types which differ from sensor outputs, transmitters are used to convert the raw output to a compatible signal. This signal may be analog or digital in ...

Process instruments consist of two main components: a sensor and a transmitter. The sensor is sometimes part of the instrument assembly, as with some pressure instruments, but is more often separate, ...

NASA lost contact with the interstellar Voyager 1 spacecraft for nearly a week after a technical glitch shut off the probe's main transmitter. Using Voyager's weaker backup transmitter ...
