[Stephen] recently wrote in to share his experiments with using the LimeSDR mini to conduct a bit of piracy on the airwaves, and though we can’t immediately think of a legitimate application for ...

XM has applied for a U.S. patent on a new method of FM modulation. Currently most cars do not include any kind of an auxiliary jack, so the method of choice for satellite radio is through FM ...

We’re getting a flavor now of more new products that will be on the exhibit floor at the NAB Show. Inovonics has introduced a fourth-generation FM modulation monitor, saying: “The new 541 incorporates ...

A look at the simplest FM demodulation technique. It doesn’t give the lowest possible output distortion, it doesn’t reject amplitude distortion effects, but it is simple and can be used at virtually ...

Modulation is the act of translating some low-frequency or baseband signal (voice, music, and data) to a higher frequency. Why do we modulate signals? There are at least two reasons: to allow the ...

The key parameters of the FSS technique and their impact on EMI performance. How to evaluate FSS performance using simulation, ICs, and a signal generator. Frequency spread spectrum (FSS) is a ...
