New National Instruments Hardware and Software Provide Dramatic Advances from Baseband to RF Engineers and scientists now can generate RF and baseband signals more than 300 times faster with the new ...

Despite the need for an IC, this ubiquitous interface between the modulator and audio-video signals has not been reduced to an integrated circuit. The major reasons for that deficiency are the ...

In Part 3 of RF Fundamentals, we will focus on the challenges related to the need to generate and demodulate analog and digitally modulated signals in the RF signal chain. We’ll review CW signal ...

Modern oscilloscopes capture, view, measure, and analyze complex RF signals in the time, frequency, and modulation domains. Time-domain analysis, the original oscilloscope function, allows users to ...

There was a time — not long ago — when radio and even wired communications depended solely upon Morse code with OOK (on off keying). Modulating RF signals led to practical commercial radio stations ...

HyperLight Corporation, creator of the TFLN Chiplet™  platform, today announced the release of its 145 GHz Packaged Intensity Modulator (IM), expanding the company‘s high-speed modulator portfolio.

Tektronix has rolled out the RTX130A, an integrated MPEG and RF signal generator offering both unmodulated and RF modulated playout of MPEG transport streams, supporting both cable (QAM A, B & C) and ...

Direct modulation of a laser 1 has always been used in optical telecommunications. Although distance–capacity product capabilities using this approach have been limited, it represents a very ...

As the number of higher-throughput applications grows, so does the need for wider bandwidth and network coverage in wireless systems. Given limited spectrum allocation, wireless communication ...

Raspberry Pi enthusiasts searching for a way to use their Raspberry Pi mini PC with an old school retro TV, may be interested in the Raspberry Pi Zero RF Modulator HAT. Using old now-defunct TVs and ...

Compared to the simple diode needed to demodulate AM radio signals, the detector circuits used for FM are slightly more complicated. Wrapping your head around phase detectors, ratio detectors, ...
