Pulse density modulation (PDM) is a compact digital audio format used in devices like MEMS microphones and embedded systems. This compact primer eases you into the essentials of PDM audio. Let’s begin ...

Doing more with less in electronics often means improving power density. One of the new areas garnering attention involves applying a variety of advanced modulation techniques, including PWM and space ...

In radio communications, one way to generate single sideband (SSB) signals is to make a double sideband signal by feeding a carrier and a modulation signal into a balanced modulator to create a double ...

Xperi and several U.S. broadcast groups are pushing back against an effort to modify the FCC’s order allowing asymmetric digital sidebands. In September the commission allowed most FM stations to ...

Abstract: We describe a microwave amplitude modulator capable of operating at high modulation rates (limited by mixer IF port bandwidth) with minimal residual phase modulation. The modulator is based ...

A vote by all five Commissioners at the September Open Meeting on a plan that would streamline the process for allowing digital transmissions at different power levels on the upper and lower digital ...

Emerging, data-intensive technologies like artificial intelligence and machine learning are gaining popularity. Data centers, which act as the essential infrastructure for these technologies, need to ...

The Federal Communications Commission this month will vote on a change to streamline the process for allowing FM digital transmissions at different power levels on upper and lower digital sidebands, ...

Modulation advances have fueled more efficient use of bandwidth, although conventional modulation formats still require allowance for upper and lower sidebands around the carrier frequency. Ultra ...

In a direct-conversion signal chain, it is often difficult to accurately predict the noise-figure impact due to an in-phase/quadrature (IQ) demodulator. Typically, the noise figure is measured using a ...
