一天掌握DFT
一天掌握DFT，绝对好文,If you're into signal processing, you will no doubt say that the headline is a very tall claim. I would second this. Of course you can't learn all the bells and whistles of the Fourier transform in one day without practising and repeating and eventually delving into the maths. However, this online course will provide you with the basic knowledge of how the Fourier transform works, why it works and why it can be very simple to comprehend when we're using a somewhat unconventional approach.The important part: you will learn the basics of the Fourier transform completely without any maths that goes beyond adding and multiplying numbers! I will try to explain the Fourier transform in its practical application to audio signal processing in no more than six paragraphs below.
