Fourier Transform Duality Rect and Sinc Functions
на канале: Iain Explains Signals, Systems, and Digital Comms
Explains how the square waveform, Rec(t), and the Sinc function are related via the Fourier Transform. They are extremely important functions in digital communications and electronics, as well as elsewhere.
* Note that in this video I used the following definition of the Sinc function: sinc(x)=sin(x)/x
** Also note that I made a minor typo when I wrote out the answer to the integral on the first line of mathematics. The -1/jw term should be positive. The line below is correct though, so I didn't carry the error through - it was just a "typo".
