  • Measuring VSWR to Quantify Transmission Line Imperfections

    Posted Jan 27, 2015 By Maxim
    Impedance mismatches in a radio-frequency (RF) electrical transmission line cause power loss and reflected energy. Voltage standing wave ratio (VSWR) is a way to measure transmission line imperfections. This tutorial defines VSWR and explains how it is calculated. Finally, an antenna VSWR monitoring system is shown.

  • RS-485 COMMUNICATIONS MICRO PLC CARD

    Posted Jan 26, 2015 By Maxim
    Industry 4.0 marks the fourth industrial revolution, characterized by distributed, intelligent control systems. Breaking from a past with large, centralized programmable-logic controllers, Industry 4.0 allows for highly configurable, highly modular factories that accept an ever-increasing number of sensor inputs and operate at a higher output than before. The ultra-small PLC, or Micro PLC, lies...
  • Combining Capacitive Sensing and LED Lighting - Pt. 4

    Posted Jan 26, 2015 By EEWeb
    In the previous installment, we explored how to overcome common challenges faced when designing systems with capacitive sensing and LED lighting. This edition will address low-power design considerations for such applications. In order to optimize power consumption, capacitive sensors are typically scanned in a repeated scan-sleep-scan-sleep routine. The sensors are scanned at a specific...
