Spread spectrum technology has blossomed from a military technology into one of the fundamental building blocks in current and next-generation wireless systems. From cellular to cordless to wireless ...

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 ...

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 ...

Electromagnetic interference (EMI) is energy that adversely affects theperformance of electrical/electronic equipment by creating undesirableresponses or complete operational failure. EMI is caused ...

Spread spectrum clocking (SSC) is used in many computer interfaces such as PCI Express and Serial ATA to improve the EMI performance of the interface. It takes the form of frequency modulation (FM) of ...
