# Discrete-time Fourier transform (DTFT)10

In the last two posts in my Fourier transform series I discussed the continuous-time Fourier transform. Today I want to start getting "discrete" by introducing the discrete-time Fourier... 更多内容 >>

# Image Enhancement: A Medley3

Can I post two silly-season items in one day? Hey, it's my blog, so why not! One of my posts that received the most comments was the one about image processing in the movies. Since so... 更多内容 >>

# A very different take on the Fourier transform5

This is my silly season entry (from... 更多内容 >>

# Continuous-time Fourier transform of windowed cosine10

Last week I showed a couple of continuous-time Fourier transform pairs (for a cosine and a rectangular pulse). Today I want to follow up by discussing one of the ways in which reality... 更多内容 >>

# Continuous-time Fourier transform basics12

In my planned (well, partially planned) discussion on Fourier transforms, I'll focus on three of the four types I listed in my November 23 post: ... 更多内容 >>

# Example of Fourier terminology confusion3

This exchange of comments between Cris and me (see comments 11-16) is a good example of the kind of terminology confusion that surrounds Fourier transforms. Cris and I both have a background in... 更多内容 >>

# Fourier transform visualization using windowing32

When I dipped my toe into the Fourier transform waters last week, the resulting comments and e-mail indicated there is a lot of interest in tutorial material and explanations. I'm willing, ... 更多内容 >>

# Fourier transforms25

Confession time. When it comes to writing about Fourier transforms on this blog, I'm a chicken. (For my readers not familiar with English slang, chicken in this context means a cowardly... 更多内容 >>

# Extracting dot locations from a graphic11

I was looking at the image below on a web page recently and I decided to extract the locations of all the dots. I thought the procedure might make a nice little end-of-the-week how-to... 更多内容 >>

# Maybe truecolor is OK after all2

Yesterday I posted that I was looking for a replacement for the term truecolor. (I won't repeat the explanation here; take a look at the original post.) Quite a few readers posted interesting... 更多内容 >>
