Hello, I am have this telecommunications formula which calculates the magnitude of a wave on a transmission line:(adsbygoogle = window.adsbygoogle || []).push({});

VO = VI e^(-yi)

where:

VO = voltage out.

VI = voltage in (5)

y = propagation coefficient (0.745 + j1.279)

i = length of line (2500)

I am trying to use it to calculate the magnitude of a wave on a transmission line that is:

- 2.5km from the source

- whose input signal is 5V

My attempt is to write it out as below:

VO = 5*e^((-0.745 + j1.279)2500)

But I am unsure if I am have written this out correctly and if so, how to take 'e' to the power of a complex number.

Any help regarding how to finish this would be greatly appreciated.
