Walter, Sounds like we will need to talk about this on Tuesday. I did notice the usage of the word "filter" in those sections, and I have no problem with them. If the Init function applies the tap coefficients, it does filter. If the GetWave function applies some other tricks, it filters. However, if the EDA tool is only expected to take the output of Init, and convolve that with the stimulus bit pattern, it does not filter anything, it simply combines them. This is why I got hung up on this. If we used the word filter for that, we open the door for all kinds of processing which I don't this was the intension. Now, how can we express these thoughts without using the specific word "convolution"? Well, in this case we may just have to use that word, but I was just wondering whether this convolution can be described in any other way without using that specific word, but without making it so vague that the EDA vendor could do anything else... Have a good weekend.

I will point out that the following words are now used consistently in sections 2.1.6, 2.2.6 and 3.1.2.1. The new impulse response is expected to represent the filtered response. So if the output of AMI_Init is the filter response, ie the channel impulse response after being filtered. Then I believe that these exact same words can be used for filtering the GetWave input as well.

It sort of implies more than "just convolution". Can we say "combines, for example by convolution" like this: | Step 4. The simulation platform takes the output of step 3 and combines | (for example by convolution) the input | bitstream and a unit pulse to produce an analog waveform.

Note that "Step 4" now says | Step 4. The simulation platform takes the output of step 3 and filters the input | bitstream and a unit pulse to produce an analog waveform. I (and SiSoft) believe that the BIRD can be submitted as enclosed.

Other than these, we can submit it as far as I am concerned. 1) Grammar: in the text of 2.1.6 we should change "pass" to "passes". 2) Kumar suggested not to use the word "convolves". Is this something we would want to eliminate from "Step 4"? 3) At the end, we should add that this was discussed on the 4/1 and 4/8 meetings: The thoughts captured in this BIRD were discussed at the April 1, 2008 meeting of the IBIS-ATM Working Group. A slide presentation of this material is available at: http://tinyurl.com/28ouvx Thanks, Arpad ======================================================================== =
