The circuit was designed to produce a 500mW output power transmitter whose signal modulated by FM using four transistors. Transmitter – an electronic device that can produce or amplify a carrier wave ...

In the first three installments of this series, we discussed whether or not an old transmitter was even worth fixing, followed by some techniques I ve used to repair high-voltage power supplies, ...

Here is a wireless FM Transmitter which uses RF communication to transmit the medium or low power FM signal with the maximum transmission range of around 2 km. Here is a wireless FM Transmitter which ...

[Angelo] is only 15, but that doesn’t mean his fabrication skills are limited to Lego and K’Nex. He’s built himself an amazingly well constructed FM transmitter that’s powerful enough to be received a ...

Pulse Width Modulation (PWM) or Pulse Duration Modulation (PDM) is a technique of converting analog signals into rectangular waveforms. The width of the waveform varies in proportion with the ...

A key component for these wireless battery power chargers is a power transmitter IC that offers robust, standalone applications capable of transmission distances up to 15mm and tolerance of poor coil ...

Researchers have developed a low-cost visible light communication (VLC) system using commercially available hardware that ...

Significant efficiency and performance improvements can be realized by improving the current loop’s power supplies, replacing linear regulators with high-efficiency buck regulators. It also increases ...

AM radios are relatively simple devices, and building one is a good way to start exploring the world of radio communications. [GreatScott] does exactly this in the video after the break, building both ...
