I have to show that the Fourier transform of f(t-a) is exp(-iwa)*F(w).
Any headstart?

Fourier Transform is a mathematical operation that decomposes a signal into its constituent frequencies. It is used to convert a signal from its original domain (often time or space) to a representation in the frequency domain.
The function f(t-a) is a time-shifted version of the original signal f(t). This means that the original signal has been shifted by a time interval of "a". The Fourier Transform of f(t-a) will also be a time-shifted version of the original Fourier Transform, with the same amount of shift, but in the opposite direction.
Fourier Transform is used in various fields of science, such as signal processing, image processing, quantum mechanics, and spectroscopy. It helps in analyzing and understanding the frequency components of a signal, which can provide valuable information about the underlying physical processes.
Fourier Transform allows us to break down a complex signal into simpler components, making it easier to analyze and process. It also helps in identifying specific frequencies present in a signal, which can provide insights into the underlying dynamics. Additionally, Fourier Transform is a powerful tool for filtering out unwanted noise from a signal.
While Fourier Transform is a powerful tool, it has some limitations. It assumes that the signal is periodic, which may not be true for all signals. It also assumes the signal is continuous, which may not be the case for discrete signals. Additionally, it can be computationally intensive for large datasets, making it challenging to analyze in real-time applications.
