October 1, 2009[Engineering Essentials] Boost Instrumentation Accuracy With Direct Digital Synthesis
Direct digital synthesis (DDS) generates arbitrary frequency sinewaves with amazing accuracy and spectral purity. The ability to generate spectrally pure sinewaves at programmable arbitrary frequencies has application in instrumentation and communications products, among other uses. Today’s DDS components provide extremely accurate, spectrally pure sinewave generation with reasonable power requirements. Modern DDS components have...

[Power Design] Solid-State Triac Devices Replace Mechanical Relays In Power Switching Applications
Mechanical relays, contactors, and switches control the flow of electricity by the mechanical action of two conducting elements. The physical contact of two conducting elements creates a path for electricity. Remove that physical contact, and the electrical pathway is broken. Mechanical relays, contactors, and switches operate in this manner. However, solid-state triac devices may be used to interrupt the flow of electricity in a manner that is synchronous with the ac current waveform.
