Are these two signals same?
Are these two signals same with respect to frequency spectrum? one is zero padded and one has two cycles. If zero padding would just add interpolated points in the original spectrum, then would the spectrum for both of these same? Signal 1 (zero padded after first cycle) Time Amplitude 0 0 1 1 2 0 3 0 4... 25 Jun 2010 03:20

Spiral Toroid
Hi. I am trying to create a model of a spiral contained within a toroid. The idea is that there is a continuous cylindrical spiral (cylinder diameter of 2) whose path is restricted to the inside of a 3D toroid (outer diameter of toroid being 150 with inner diameter of 50). The cylindrical spiral should be packed as c... 16 Jun 2010 03:26

implementing a flanger in MATLAB
Hello everyone, I've been experimenting in MATLAB, attempting to create a flanger type effect. I'm fairly certain that the flanger is already included in a toolbox but I would like to create one on my own for personal satisfaction. I've been reading up on flanger operation but I've had trouble recreating the effect.... 22 Jun 2010 16:02

Histogram of non uniform samples.
I need a way to interpolate data that was non uniformly sampled so that I can create a histogram. The data collection has three states. While the device is sleeping, the temperature is sampled every 60 mininutes. When the device is cooling, the temperature is sampled every 10min. When the device is heating, the tempe... 16 Jun 2010 01:16
