The U.S. Air Force Research Laboratory is asking industry for digital signal processing technologies to detect and analyze high-priority radio frequency (RF) signals for intelligence and cyber ...

The distinction between analog and digital signals is very simple, but it can still be a challenge to wrap one's mind around the concepts that define the two systems. Just when you think you've got it ...

Fundamental to all wireless communications is modulation, the process of impressing the data to be transmitted on the radio carrier. Most wireless transmissions today are digital, and with the limited ...

Learning Digital Signal Processing (DSP) techniques traditionally involves working through a good bit of mathematics and signal theory. To promote a hands-on approach, [Clyne] developed the DSP PAW ...

A digital signal processor (DSP) is a specialized microprocessor that performs mathematical operations with lightning speed. For instance, a DSP might perform the mathematical operations necessary to ...

Signals are electrical or electromagnetic means of conveying and transferring information. Logic signal switches are binary transducers, meaning they take these electrical or electromagnetic signals ...

A signal is an electric current or electromagnetic field used to convey data from one place to another. Signal converters are electronic devices that receive one type of signal and output another type ...

(1) An electronic signal transmitted as binary code that can be either the presence or absence of current, high and low voltages or short pulses at a particular frequency. (2) A common classification ...
