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 ...

Modulation is the process of adding audio to a transmitted signal ... In this case, distortion from transmitter through the receiver detector measured 5.1%. It was only 3.1% at 90% modulation. Fig. 6: ...

This is generated in the transmitter, and if it is radiated in this form it carries no information – it appears at the receiver ... known as Amplitude Modulation (AM). Figure 3-2. An amplitude ...

Have you ever heard terms like modulation scheme ... of the quality of an RF link as the ability of both the transmitter and receiver to preserve the desired phase, magnitude, and frequency ...

The process of designing a short-range radio ... Running a frequency-base form of modulation allows the transmitter to operate as a CW signal, which cuts back on the kicking effects suffered ...

“No modifications were needed to a standard AM receiver ... Modulation System, “we’re grabbing the sidebands and bringing them up to the amplitude of the carrier so that sideband energy equals the ...

Other types of modulation schemes such as FSK provide a much cleaner output, but require a clear channel –however that is another discussion. Antenna lengths for both transmitter and receiver are ...

Direct modulation of a laser 1 has always been ... design and the use of digital signal processing (DSP) at both transmitter and receiver to compensate for the non-ideal phase and amplitude ...

For those building their own remote controlled devices like RC boats and quadcopter drones, having a good transmitter-receiver setup ... as the reverse engineering process needed to obtain this ...

Whether you need a headphone adapter, a Bluetooth receiver for your home-audio setup, or a Bluetooth transmitter for your ... no problems during the pairing process. Plus, this model supports ...
