Please chat about this (and other brainstoming questions) here, rather than on the main site. Thanks!

But, if some awesome user wanted to start a meta post, build a data explorer query, or otherwise help out with this, that would be great and get the ball rolling (Or I can do it tomorrow evening...)

The question is poorly worded, but it could be fixed and the answers are quite wrong.
You *can* set up XCode for cross compilation (see, for example, [this Stackoverflow question](http://stackoverflow.com/questions/1941494/add-a-custom-compiler-to-xcode-3-2), [this forum discussion](http://forum.soft32.com/mac/extend-Xcode-gcc-cross-compile-gcc-work-ftopict47512.html] and [this cross-compilation guide](http://www.ethernut.de/en/documents/cross-toolchain-osx.html) ). , any guide to set up an AVR (or ARM) cross-compile target for

@IvoFlipse, @everyone else, I'd love to do some projects with an NXT sometime in partnership with SU and this SE site. After my final exams are over, I'm going to try contacting NI and LEGO about getting a set (or at least a discount) for a review

@community, other SE sites have been deemed graduating material and then there have been delays as long as 3 months, it takes a lot of work to graduate a site, you will know when it is about to happen.

it is just a set of impulses that are spread out evenly in space, the you multiply by your image to get a set of impulses that represent your image in discrete space.

Autoregressive moving average model

In statistics and signal processing, autoregressive moving average (ARMA) models, sometimes called Box-Jenkins models after the iterative Box-Jenkins methodology usually used to estimate them, are typically applied to autocorrelated time series data. Given a time series of data Xt, the ARMA model is a tool for understanding and, perhaps, predicting future values in this series. The model consists of two parts, an autoregressive (AR) part and a moving average (MA) part. The model is usually then referred to as the ARMA(p,q) model where p is the order of the autoregressive part and q is th...

Normally you have some form of autoregressive moving average system. It has feedback from the last point and multiple inputs feed in.

Jan 18, 2011 14:04

pulse time and discrete time are equal.

Kortuk

Jan 18, 2011 13:59

For example, audio samples at 41kHz, this is significantly faster than an audio signal, so you do not loose data, and then you just store a set of data points in memory that represent a the original signal, but in discrete time, also called pulse time.

Kortuk

Jan 18, 2011 13:58

in a computer you cannot store a continuous signal, but you can sample it.

Kortuk

Jan 18, 2011 13:57

it is just a 2d impulse train.

Kortuk

Jan 18, 2011 13:55

@tina, at the point on page 11 when they do the comb function they are trying to show you how it is sampled from continuous to discrete.

Kortuk

Jan 18, 2011 13:55

If you have it on your computer you already have a discrete image.

Kortuk

Jan 18, 2011 13:54

If you can load the image into memory, like into a matrix in matlab, you already have it in discrete form.

Kortuk

Jan 18, 2011 13:53

@tina, if you have already got the picture in digital form it is already sampled. They are trying to explain the correlation between a pulse train and a continuous time signal and how it is sampled.
