Convolution Tutorial
 

I have created a tutorial on the convolution integral. It uses an
interactive flash program with embedded audio files.

It is located he

Brent,

Just wanted to thank you for preparing all your Flash tutorials.
Really helps to get insight into these topics. I wish I had these
when I was struggling in Electrical engineering classes.

Have a great New Year - Roger

Hi Brent,
maybe I am missing something.
The 1-D convolution outputs that you show don't seem quite right?

could you be more specific?

Hi Brent,

thank you very much for all your Fourier series, DSP , Smith chart,
etc.. flash tutorials. Very nice and helpful !

73's and Happy New Year

When I examined the convolution of a sine wave and a pulse, the
trailing part of the output waveform after the pulse was processed,
seemed to have a random component od small amplitude round zero.

I am sorry, but I don't see it. I can say that sometimes you have to
push the slider kind of slow to catch all the points. If the slider
is pushed too fast the program interpolates the points that were
missed.

I believe you have identified the issue: selecting pulse (That's the
wider one) and freq2 (that's the higher f), then if I pull the slider
too fast, the trace is jagged - which is as you say like hopping over
samples.... Pulling the slider SLOWLY fixes this right up!

Thanks
