Phase Shift and Time Shift - Fourier Transform

Click For Summary
SUMMARY

The discussion focuses on the relationship between phase shift and time shift in Fourier Transformations, specifically addressing the equation x(t-t_0) → e^(jωt_0)X(jω). A participant expresses confusion regarding the simplification process, while another clarifies that the correct transformation should be x(t-t_0) → exp(-jωt_0)X(jω), highlighting the importance of the negative sign in the exponent. This correction is crucial for accurate application of Fourier Transform principles.

Homework Statement



I'm trying to relate phase shift and time shift Fourier Transformers

Homework Equations



x(t-t_0) → e^(jwt0)X(jw)

The Attempt at a Solution



I've attached a picture of my work. I'm a bit confused as to how I would be able to make that simplification towards the end.

How about x(t-t0) → exp(-jωt0)X(jω)? Note the - sign in the exponent.
