LFSR

Description:

This is a Community containing all things related to Linear Feedback Shift Registers (LFSRs) and their use or mathematical basis. LFSRs are used for Cyclic Redundancy Check (CRC), Parallel Signature Analysis (PSA) and pseudo-random pattern generation with Built-In Self Test (BIST) as well as pseudo-random number generation to list just a few applications.

Yesterday I went to a seminar sponsored by NuHorizons the purpose of which was to present Linear Technology's free LTspice program. Mike Engelhardt whose job at Linear Technology is to continually develop the simulator gave the seminar. Who is a better person to ask a question of pertaining to a program than the author himself?

Bibo thanks for sharing your pseudo random bit sequence function. I hadn't heard about Scilab but it sounds interesting and its always good to have a freeware alternative to a popular software package. What are you using it to do?

In Excel you can write Visual Basic macros to do just about anything. Someone could write (and share) functions for all the boolean operations that could be called just like they are built into Excel itself. In fact I've done it for some functions that are rather difficult to do within Excel. The only downside to it is that you get security warnings when you open a file about whether to enable macro functions or not. There are some conversion (bin2dec, dec2bin, ...) routines built into Excel but they are limited to 10-bits so making more flexible versions would also be nice. I haven't gotten a copy (yet) but I've heard good things about the book "Excel by Example: A Microsoft Excel Cookbook for Electronics Engineers"

Does anyone know if it's possible to do logic operations on data in Excel spread sheets (like AND, NAND, OR, NOR, XOR...). I'm not talking about conditions like "IF this OR that...", I'm talking about XORing two pieces of integer data together.

Hi all!

I am interested in and confused by LFSRs too!

I have written a function in Scilab(An open source Matlab alternative) for generating PRBSs. Hopefully it will be helpful to members of this community. The link follows:

Welcome to all!

Let us all share in these interesting and practical application of mathematics.
