I'm taking the fourier transform of a signal. This integral has bounds from -∞ to ∞, but since the signal is 0 for negative t, the bounds become 0 to ∞(adsbygoogle = window.adsbygoogle || []).push({});

doing the integration, the antiderivative I get is e^{t*(-3-jω+2j)}where j is sqrt(-1)

Now I have to evaluate this at t=infinity (since it is a proper integral)....I don't really know how to do this since (-3-jω+2j) is a complex number.

infinity times a negative number is negative infinity

infinity times a positive number is positive infinity

infinity times a complex number?????

any help will be appreciated,

thank you very much
