Recognize the design issues and the advantages and disadvantages related to analog and digital transmitter architectures.

Understand the challenges of realizing a universal CMOS RF transmitter.

This book describes a novel idea of RF digital-to-analog converters (RFDAC) and demonstrates how they can realize all-digital, fully-integrated RF transmitters that support all the current multi-mode and multi-band communication standards. Somehow, they said, they’d manage.With the proliferation of wireless networks, there is a need for more compact, low-cost, power efficient transmitters that are capable of supporting the various communication standards, including Bluetooth, WLAN, GSM/EDGE, WCDMA and 4G of 3GPP cellular. They reminded me that for most of their TV years, they actually had to get up off the couch toĬhange volume or channel. I offered to grab them a universal remote from Radio Shack, or even to arrange for a second cable box, but they declined.

The converter box’s incredibly cheap remote is good only for changingĬhannels the TV’s original remote is still necessary for on/off and volume. The only hitch: now they had two remotes to worry about. Over all, my parents were delighted with their switch to digital over-the-air TV.

We discovered, in fact, that each time you change the channel, the converter box displays an information banner at the top of the screen, identifying the TV show, the channel, the time slot and other details. That it started pulling down was sharper and clearer than it had ever been on that TV. I hooked it up in about a minute - and presto, the digital picture The converter box was as cheap and basic and hollow-feeling as you can possibly imagine, but at least the wiring diagram was extremely clear.

Is an upstairs TV that’s used only occasionally, and the channels provided by free, over-the-air network broadcast signals suffice.) (Their main TV has cable, so it doesn’t need the converter box. The government - it looked like a red credit card, they said - and had cashed it in at an electronics store. Yes, my parents had received their $40 coupon from One of them involved hooking up a TV set to one of those new analog-to-digital converter boxes, in readiness for the nation’s switch to all-digital broadcasts. By mutual agreement, they had saved up all their technology problems for me to fix during When I spoke in Cleveland, my hometown, a couple of weeks ago, I stayed with my parents, which was a nice blast from the past.
