Lecture 35B: Principle of Duality, The Circular Convolution.

This video looks at the differences between the DFT (Discrete Fourier Transform) and the FT (Fourier Transform) and why the DFT ...

Why do discrete time signals exhibit a repeating pattern in their frequency spectra? When we sample a signal, turning it into a ...

Convolution and the Fourier Transform go hand in hand. The Fourier Transform uses convolution to convert a signal from the time ...

The #FFT is so efficient because it breaks the problem down into little bits and performs the same 2-point #DFT calculation on ...

The output of the FFT can be quite confusing. All you are presented with is a list of complex numbers that, at first glance, don't tell ...

If you've ever looked at the magnitude spectrum of a signal after performing an FFT, you'll notice that it is symmetrical about a very ...

i and the Fourier Transform; what do they have to do with each other? The answer is the complex exponential. It's called complex ...

What is negative frequency? Why do we need it? What have imaginary numbers got to do with it? Is it a physical phenomenon or ...

How can breaking a problem into smaller parts lead to massive efficiency gains in the DFT? In this final lecture of a four-part series ...

The output of the FFT is just a list of complex numbers. But, we are used to seeing the FFT of a signal represented as a graph of ...

In this engaging introduction to the Fourier Transform, we use a fun Lego analogy to understand what the Fourier Transform is.

Twiddle Factors play a crucial role in the Fast Fourier Transform (FFT) algorithm. They are the workhorses of the algorithm, acting ...

Twiddle Factors play a crucial role in the Fast Fourier Transform (FFT) algorithm by helping to combine and manipulate the ...
