Taking data from 2 boards at different speeds
I am working on a project that requires the monitoring of temperature and pressure in an internal combustion engine. For some reason, the lab is running labVIEW 6, even though we have a free site license for 8.5. We are using a PCI 6070E and a PCI 4351 connected to TC-2190 and BNC-2010 terminal blocks. I need to collect data from these two at the same time, when I do this the data from the BNC overruns its buffer, and the TC has erratic read rates. They need to read at different rates. I am pretty new to labVIEW and my code is a mess, so I won't post it as it is nowhere n...Implementing NLMS for Echo cancelation in Speech
I am trying to write an acoustic/line echo canceller.
I choose the quite well known nlms algo.
First I tried to implent it in matlab.
When I checked the algo with any "test input" like sin wave, zigsaw etc,
I did get convergance.
Then I tried it with speech, but failed.
I tried to improve it by implementing anti-correlation filter
Pre-whitening). I did saw minimal improvments in the filter taps, and i
terms of math output, there is error reduction ( not much). Still, whe
you play the speech, you dont hear a difference.
I also implemented filter which cut all 0-100Hz fully, 100-...Echo GP
Does anyone have a manual (preferably scanned) for the Echo GP? I can
find lots of info for the Echo cards, but nothing for the standalone
GP. I know the one I have works, as I plugged it into my PC's serial
port and it speaks. There are supposed to be special commands that you
can send to the device to control pitch, speed, pronunciation of
punctuation, phoneme mode, etc., but I don't have any of that info. I
have Googled extensively without success.
...Synchronous but different iterators
(somewhat contrived example:) Say I have 2 different data structures
which I want to iterate over, and Tree, and an Array. I had to write
specific iterators for my Tree structure, such as depth_first,
breadth_first, etc. Is there a good way to iterate over each
structure in a synchronous manner, but with a different iteration
For example, I want to step through my Array normally using
each_index, but want to step through my Tree structure using, say,
depth_first, but I want to do this concurrently because of what I want
to do to/with the data.

one obvious way is to put every command in an echo statement.

in two places. Is there any other way to achieve this?

How an echo canceller distinguishes that an incoming stream of bits

It's all data isn't it? The issue is reliably reconstructing the bits at
the output. If there's echo / multipath, then that's still the objective.

How do I calculate number of days different?
ex: beg date 20060205

I need to know how many days different?
What is the function syntax to handle this?
thanks for your help
You can use the %diff built in function to return the difference between two
date, time or timestamp values.
For example: day_diff = %diff(end_dat::beg_date:*days);
Hope this helps

...plot with different ranges
I want a fit function to be plotted only in a special range:

however seems not to work.
Is this somehow possible ? If not, then this could mean that I would have to
use another tool, simply because I can not print a fitfuntion in the whole
graph because that would mean that the fit is relevant in the whole plot
which is not true.

I am new to common lisp, and just do some exercise in REPL. REPL will

My questions, how to close the echo in the following situation:

(dotimes (i n result)
(setf (svref result i) (random limit)))))

What can you do with a _TEMPORARY_ array that cannot not be done
length _temporary_1 - _temporary_100 $ 5
_temporary_101 - _temporary_300 $ 1
array _temporary_ (100,3) _temporary_1 - _temporary_300 ;
retain _temporary_ ;
drop _temporary_: ;
Or perhaps a better question is, what will you do with the 800
bytes that be saved by not using
array _temporary_ (100,3) $ 5 _temporary_ ;
In general, non-problems are better not solved.
