Signal reliability is paramount in many wireless applications. For example, crane controls or other critical control equipment must not lose connection as the equipment moves. Stage actors must ...

Fig 1. In a typical PWM controller in which the active devices are driven by a simple square wave, a Fourier representation of the clock’s frequency spectrum consists of the fundamental switching ...

A radio technique that continuously alters its transmission pattern either by constantly changing carrier frequencies or by constantly changing the data pattern. DSSS multiplies the data bits by a ...

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 ...

As an engineer, you know how fast consumer electronics devices operate and how many tasks they perform in fraction of second. High-speed operation of these devices has made possible the many pleasures ...

[Michael Ossmann] spoke on Friday to a packed house in the wireless hacking village at DEF CON 25. There’s still a day and a half of talks remaining but it will be hard for anything to unseat his ...
