Most often ultrasonic transducers are used for distance measurements, and in the DIY world, usually as a way for robots to detect obstacles. But for a weekend project, [Vinod.S] took the ...

building both a transmitter and receiver. At the most basic level, AM radio works by generating a carrier wave with an oscillator, and then modulating the amplitude with an audio signal.

which is the maximum distance that the transmitter and receiver can be separated and still communicate data rate, which is the amount of data in bits per second that can be transmitted and output ...

Lockheed Martin MS2, Owego, New York, has been awarded a maximum $30,814,317 delivery order (THD9) against contract SPRWA1-13-D-2000 for transmitter receivers. This is a firm-fixed-price contract.

In space exploration, long-distance optical links can now be used to transmit images, films and data from space probes to ...

If you’re new to using wireless mics with your smartphone then this ‘plug and play’ kit from RØDE comes highly recommended.

Reaching indoor antennas requires more power, offsetting efficiency gains made by today’s solid-state technology ...

Four-wave mixing A weak optical signal (red) from a spacecraft transmitter can be amplified noise-free when it encounters two pump waves (blue and green) in a receiver on Earth. (Courtesy: Chalmers ...

In space exploration, long-distance optical links now enable the transmission of images, videos, and data from space probes to Earth using light. However, for these signals to travel the entire ...
