The paper deals with the immunity to Electromagnetic Interference (EMI) of current source for Ultra-Low-Voltage Integrated Circuits (ICs). Based on properties IC building blocks, such as current-splitter and correlator, a novel generator is conceived. proposed solution suitable provide currents ICs operating in sub-threshold region even presence an electromagnetic polluted environment. EMI comp...
AbstmctMultiuser CDMA detectors suppress interference to provide improved noise immunity, increased capacity, higher data rates and reduced precision requirements for power control. A new multiuser detector structure is formulated which offers a number of implementation modes ranging in performance from that of interference cancellation (IC) detectors to that of linear receivers, yet provides m...
Radio controlled clocks (RCCs) based on the WWVB broadcast, commonly referred to as “atomic clocks”, might experience relatively high levels of on-frequency interference from the equivalent MSF time-code broadcast from the UK, particularly on the East Coast. The problem may be further exacerbated by a random orientation of the RCC device, which might favor the reception of the interfering signa...
Wireless telephone-hearing aid electromagnetic compatibility research at the University of Oklahoma.
A multiphase study examining electromagnetic compatibility (EMC) between wireless digital telephones and hearing aids has been under way at the University of Oklahoma EMC Center since May 1995. In a phase 1 clinical study involving 68 hearing aid wearers, interference varied significantly by telephone technology, hearing aid type, and hearing loss characteristics. More than 80 percent of the te...
We have developed the effective algorithm for detecting digital binary phase-shift keyed signals. This algorithm requires a small number of arithmetic operations over the signal period. It can be relatively easy implemented based on the modern programmable logic devices. It also provides high interference immunity by identifying signal presence when signal-to-noise ratio is much less that its w...
Modern train interval control systems contain communication channels between traffic organizers and the locomotive, using rail inductive as lines. The threads that make up these lines are an integral part of traction network and, therefore, current is channeled through them. Bearing this in mind, signals operate under conditions strong interference from current. At present, continuous automatic...
Audio mixing greatly degrades the watermarking security. Consequently, it is of importance to introduce mixing-attack-proof audio watermarking algorithms. This article investigates audio mixing attack. A randomized embedding spread spectrum audio watermarking algorithm is accordingly proposed to improve the watermark immunity to mixing attacks. First, balanced modulation is introduced to get ri...
In this paper the problems associated with immunity of embedded systems used in Motor-Drive systems are investigated and appropriate solutions are presented. Integration of VSD motor systems (Integral Motor) while partially reducing some of these effects, adds to immunity problem of their embedded systems. Fail safe operation of an Integral Motor in arduous industrial environments is considered...
Until the early 1990 s, incidences of Mycoplasma pneumoniae (MP) infection showed three to five year epidemic cycles in multiple countries, however, the mechanism for the MP epidemic cycle has not been understood. Here, we investigate the determinant of periodicity in MP incidence by employing a mathematical model describing MP transmission dynamics. Three candidates for the determinant of peri...
This application report introduces the concept of electromagnetic interference rejection ratio (EMIRR IN+) as a measure of the immunity of an operational amplifier to responding to electromagnetic interference (EMI). Texas Instruments has developed the ability to accurately measure and quantify the immunity of an operational amplifier over a broad frequency spectrum extending from 10 MHz to 6 G...
