Fourier Transform of a Cosine Example
Remember: complex numbers can be thought of as (realimaginary) or (magnitudephase) Example: Fourier Transform of a Cosine f(t) = cos(2πst) F(u) |
Phase Shift is a shift when the graph of the sine function and cosine function is shifted left or right from their usual position or we can say that in phase shift the function is shifted horizontally how far from the usual position.
Generally, functions are shifted (π/2) from the usual position.
Does Fourier transform account for phase?
This phase information is also expressed in the Fourier transform and can be recovered with the numpy “angle” function.
If we look at the phase value at the same index as the frequency with the maximum magnitude, we can identify the phase offset associated with that frequency component.
