The advances over the last several decades in hardware and digital signal processing have made digital transceivers much cheaper, faster, and more power efficient than analog transceivers. More ...

We now consider the performance of the digital modulation techniques discussed in the previous chapter when used over AWGN channels and channels with flat fading. There are two performance criteria of ...

This application note introduces the concepts of digital modulation used in many communications systems today. Emphasis is placed on explaining the tradeoffs that are made to optimize efficiencies in ...

We all love our wireless devices. We want more features, higher data rates, and improved range. These demands, in turn, require advanced digital protocols. Meanwhile, the number of signal sources is ...

If you’ve been shopping for a new TV at any point in the last decade, you’ve probably run across the industry’s favorite tech terms, like brightness, contrast ratio, black levels, and even high ...

Digital pulse width modulation (DPWM) has become central to modern power conversion, enabling precise control of switching devices in DC–DC converters, inverters and motor drives. By moving the ...

Modulation is the process of varying a higher frequency carrier wave to transmit information. Though it is theoretically possible to transmit baseband signals (or information) without modulating it, ...
