I have a Signal which represents the phase response of a System
This Signal amplitude is between -pi and +pi
The problem is that the signal is full of phase jumps (greater or equal pi) (it looks a bit like this: http://tinyurl.com/yly3z4)

So i want to unwrap it to get a continuous Signal (without the borders -pi ... +pi)
it would look like this one

For non signals there are some good wrap objects which can be used even for unwrapping
As attachment an example found in the pd mailing list
I just don't know how to build this thing for signals e.g with the wrap~ object

http://www.pdpatchrepo.info/hurleur/unwrap.pd

i got a signal with a changeable block size (default is 64)
and i got an array the same size like the signal

what i want to do is multiply the Block (with its xy Samples) with the Array
Block[0] * Array[0]
Block[1] * Array[1]
...

hi, im new to pd so plz be kind

i'm trying to make a grid and/or labeled axes for an array
it should look like this

I found the patches drawpolygon-help.pd and drawnumber-help.pd but can't figure out how i define in which window the polygon is drawn

thx for you help

big thx, after a time handling with other problems i finally came back to this one
and your suggestion works absolutely perfect (until now )

i always had problems with tabreceive~,tabsend~ in combination with drawing arrays of signals diffrent blocksize but using it in this way just works fine

i think i found a way to do it
with the tabsend~ object i can write the signal instantly into a table
then i can you index and a until function to write the multiplication into a third array
i hope this can be done fast enough (before the table gets the data of the next signal block)

if there is a more effective way to do so i'm still interested in a solution

thx, i found a patch called all_about_arrays.pd
there are listed some options to add x and y ticks and lables

yes i know that, but i'd like to have some additional lables and axes
e.g. to see the elapsed time and the max/min value of the signal amplitude
