PREFLOP GUIDE FOR RAISING FIRST IN 6 Preflop Charts The ranges that follow, are the hands you should Raise First In (RFI). In other words, these are the hands you should play preflop when the action folds to you, and you should play them by raising. The best way to approach RFI is to pick a range of hands which you believe is strong
Chapter 1 – Some Fundamentals. To solve interference problems, we must understand them. So we'll begin by describing the ways that RF interference is coupled into equipment and detected. There are several principal mecha- nisms at work. You should study this tutorial thoroughly to understand how these things work.
Good RF engineers are currently at a premium, and I suspect that they always will be. The reason is partly at least to be found in the scant coverage which the topic receives in university and college courses.
RFI – Radio Frequency Interference A disturbance generated by external source that affects an electrical circuit by electromagnetic induction, electrostatic coupling, radiated or conducted. EMI – Electromagnetic Interference Also called radio-frequency-interference (RFI) when in the radio frequency spectrum,
Understanding and Solving RF Interference Problems Page 2 close to resonance will work better than one that is not. Long antennas tend to pick up more RF than short ones. Think about these fundamental principles when trying to diagnose which cables are bringing your RF into a given system (or radiating their trash into your receiving antenna).
Key criteria defined in these documents are frequencies of interest, RF Fields (i.e., Magnetic (or H-Field), Electric (or E-Field), Plane Wave (PW), and Microwave (MW), the SEdB, and the test methodology to be used to verify the SEdB. The most commonly used are MIL-STD-285 and IEEE-299.
This document provides guidance on locating and resolving issues with radio frequency interference (RFI) for non-commercial systems like TVs, radios, and amateur radio equipment. It recommends starting with checking the receiving equipment and installation.
