Video: What are Digital Systems? (Part One – The AND, OR, NOT gates)
This is part one of the basics in Digital Systems. Beginning with the existence of Boolean Algebra, take on the form of “true” and “false”. This area of thought process is called “Deductive Logic”. This presentation explains the three most common gates, its meanings and how it relates to Boolean algebra. The fundamentals to Digital […]
TI’s new 28-V, 500-mA step-down converter provides highest efficiency at light loads
Texas Instruments Incorporated introduced a synchronous, 28-V, 500-mA step-down DC/DC converter that can operate at less than 5 uA during “sleep” mode. The new TPS62175 maintains high efficiency during light load operation, while supporting ultra-low power microcontrollers that operate in 12-V, 15-V and 24-V applications, such as industrial sensor, smart meter, medical and wireless power […]
NASA Glenn’s GreenLab facility researches algae for alternative fuel
During a recent visit to the NASA Glenn Research Center in Cleveland, Ohio, my colleagues and I were taken on a tour on the GreenLab research facility. Dr. Bilal M. M. Bomani demonstrated and explained how and why the lab is in existence and the purpose it serves. At first glance, you would not know […]
