A basic AM transmitter requires an oscillator for carrier generation (like ICL8038), a modulator circuit (often using a transistor like BC547), an audio amplifier for the message signal, coupling ...

The result was the HD-64. It sits inside the C64 in place of the original RF modulator. It uses an interleaver socket to capture digital signals going to the VIC II. It then feeds these signals to ...

The result is clean, full-HD output over HDMI with no signal noise. The HD-64 module replaces the RF modulator on the C64 motherboard and supports both PAL (50Hz) and NTSC (60Hz) standards.

To test the concept, a large scale is made from foamcore and four load cells which feed into an Arduino which in turn is connected to a laptop for a visualization. After a brief test with a toy ...

This modular upgrade for your classic computer replaces the entire OEM RF modulator daughterboard with one that sports a Xilinx Spartan-7 FPGA. This chip implements the entire output stage of the ...

Abstract: The number of different radio systems is currently increasing in portable devices like mobile phones due to the wider range of applications that require an optimized wireless communications ...

Spatial control of the phase and amplitude of a laser beam is useful for applications ranging from imaging and holography to interferometry and optical tweezers, reports Neil Savage. Digital ...

Abstract: This paper presents the evaluation of radio over fibre (ROF) capability with electroabsorption modulator (EAM) as a downlink photodetector (PD) and uplink radio frequency (RF) modulator. The ...

This library is a Arduino-friendly version of TinyUSB stack. It is designed with structure and APIs that are easily integrated to an Arduino Core. There are 2 type of supported cores: with and without ...
