Transmission line reflection coefficient

  1. Mar 15, 2012 #1
    Hello, I am looking at the following calculation for the reflection coefficient of a transmission line using the formula ((ZL - ZO) / (ZL +ZO)
    I can understand it all apart from the last part (0.355e^j).
    Can someone please tell me how that figure was gained from (-0.354 + 0.030j)

    (216 + j15 - 452.38) / (216 + j15 + 452.38)

    = (236.38 + j15) / (668.38 + j15)

    = -0.354 + 0.030j

    = 0.355e^j

    hello fran1942! :smile:

    (try using the X2 button just above the Reply box :wink:)
    0.355 is the magnitude (the modulus) of the complex number -0.354 + 0.030j (use Pythagoras :wink:)

    the ej must be a misprint for e,

    where θ is … ? :smile:
