FREQUENCY-MODULATION, or the technique of varying the frequency of radio waves for signalling purposes, has been known and used for many years ; but it was not until Armstrong in the United States in ...

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 ...

Inovonics has stopped manufacturing its 531N FM Modulation Monitor after 20 years. That’s it and there ain’t no more. “The model 531 has been a popular product since its launch in 2003 with over 5,000 ...

I'm planning to get my sister an MP3 player for her birthday: Ipod or Zune, either way. The player isn't the question.<BR><BR>If I get her one, she's going to want to listen to it in the car. This is ...

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 ...

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 ...
