What are some applications of FFT in NumPy?
FFT, or Fast Fourier Transform, is widely used in signal processing, image analysis, and solving partial differential equations.
Can you give me an example of how to use FFT in a signal processing task?
Sure! You can use NumPy's np.fft.fft
to compute the FFT of a signal, which helps in analyzing its frequency components.
What kind of signals can I analyze with FFT?
You can analyze various signals, including audio signals, time series data, and even images by transforming them into the frequency domain.
Are there any limitations to using FFT?
Yes, FFT assumes the signal is periodic and can introduce artifacts if the signal is not properly windowed.
