yup on the FFT, u could easily write the PSD using xcorr and fft, i think.

what it is really lacking in is all the yummy filter routines from the 
sig proc toolbox. There are a couple of filter routines at the octave 
repository at U 0f Vigo, a yule walker and a kaiser, and an fir, i think. 
A group at auburn, i think, just released a really bitchin' controls tool 
box, replete with ss2tf tf2pz, etc. 

	Basically, if u just want to design some stuff, u can do a pretty 
good job, but if u are in an undergrad program and somebody wants u to 
hand in something with a cherbyshev or a butter ala matlab' u are out of 
luck.
	Thanks,
