These scales are calledthe radially scaled parameters and they are both very important and often overlooked.With these scales, you can determine such factors as VSWR (both as a ratioand in decibels), return loss in decibels, voltage or current reflection coefficient, andthe power reflection coefficient.The reflection coefficient () is defined as the ratio of the reflected signal to theincident signal. For voltage or current:and E refE inc(26-15)or I ref. (26-16)I incPower is proportional to the square of voltage or current, so:P pwr 2(26-17) pwr P ref.(26-18)P incExample: Ten watts of microwave RF power is applied to a losslesstransmission line, of which 2.8 W is reflected from the mismatched load. Calculatethe reflection coefficient: pwr P ref(26-19)P inc pwr 2.8 W(26-20)10 W pwr 0.28.(26-21)The voltage reflection coefficient () is found by taking the square root of thepower reflection coefficient, so in this example it is equal to 0.529. These points areplotted at “A” and “B” in Fig. This powerful application comes up with support for the most popular cameras from Nokia, Casio, Pentax, Picoh, Samsung, Hasselblad, Leica, DJI, and a wide range of other wave ratio (SWR) can be defined in terms of reflection coefficient:Downloaded from Digital Engineering Library McGraw-Hill (© 2004 The McGraw-Hill Companies. ![]() Choose the output destination, set the rules, and the output format before starting the conversion process.
