TRAINING AND SEMINARS
Analog eLab: Exploring the SPICE simulator TINA-TI: This SPICE-based simulation program is now available to the design community free from Texas Instruments. This powerful application program can perform DC, AC, noise, transient and Fourier analysis. In addition to an intuitive schematic capture user interface, the program will perform a repeated analysis on a circuit as a component is stepped through a range of values. Comparison of results between TINA-TI and those obtained on the lab bench proves the simulation to be very accurate when employing good models. On September 14th, join our panel of experts for a discussion and hands-on demonstrations of how to fully leverage the power of this uniquely capable SPICE simulator from TI. Register for this free Webcast.
Practical Analog Design Seminar: Staff Scientist Ron Mancini will present a free seminar entitled “Practical Analog Design” in several U.S. and Canadian cities. Mancini will cover topics that include a comparison of voltage and current feedback amplifiers, signal integrity, and PC-based circuit design tools from TI.
Video Compression Webcast: Register for the free webcast, “Video Compression: Evaluating System Tradeoffs with H.264, VC1, and Other Advanced Codecs,” and explore how codecs differ in terms of the tradeoffs they make between compression rates, encode/decode processing requirements and key system factors such as latency. Scheduled for July 21, this Net Seminar will provide a brief introduction to how video compression is achieved and insight into why advanced video codecs and specific profiles within these codecs are better suited for certain applications.
