"Most people think that analog is dead," notes wireless sector expert Nikhil Hutheesing, adding "But analog is still a rapidly growing part of the semiconductor business."

In his Forbes Wireless Stock Watch, he explains, "And there is really only one company that provides a soup to nuts analog system for wireless infrastructure products.: that company is Analog Devices (NYSE: ADI)." Here is his review.

"Digital chips, which store data in ones and zeroes, operate by differentiating between on and off signals.

"Analog chips, by contrast, process gradations and are able to process waveforms such as speech, music and video. So analog chips create a bridge to the digital world where data is stored and manipulated.

"Digital chips themselves are ill-suited for communicating.As digital circuits shrink to ever smaller sizes, the value in the analog portion, that doesn't scale well, continues to rise.

"A year ago, I would not have recommended Analog Devices. The company was struggling. From 2004 to 2007 ADI posted a 1% compounded annual growth rate in revenues and earnings per share.

"During that time, the company was a provider of handset basebands (modems inside a phone) which really became a commodity business. It was also in the PC power management businesses, which was also a drag on the overall growth of the company.
