how can a BILBO can be used as a pseudo-random pattern generator.(using labview) Can someone please give me an insight on how to do this asap, i would be exteremely grateful-thanks.

Dear Deano,

I am unfamiliar with the use of BILBO cells, but am willing to help as much as I possibly can. I managed to find a rather helpful website, which described the 4 functions a BILBO register is capable of – including pseudo-random pattern generation. A very versatile little circuit, I must say.

Perhaps you could take a look at the website yourself, and confirm that this is the functionality you are interested in...

Could I also ask you to provide some more information about what you are trying to achieve. Generally, the more information you are able to provide on these forums, the more users will be willing to help.

So my question to you is... are you trying to mimic a BILBO's functionality (using LabView) or talk to a piece of BILBO hardware (using Labview)? If the later is the case, could you let us know how you trying to communicate with the device.

However, if the former is the case, and you are purely interested in random sequence generation, perhaps you should consider some of the LabView functions. They may be able to provide a more efficient means of producing random patterns. Obviously, the “random number function” springs to mind. You could easily use this in conjunction with a “less than” function to produce a random digital bit.

Please also provide the version of LabView and Measurement & Automation Explorer you are using.

Thanks you for your time,

Best wishes and kind regards,

RER the link was perfect. What i want to know is how i can draw this exact circuit in labview because labview does not have any flip flops. and also show the results. Thank you very much for your help.

and yes i am trying to mimic a BILBO's functionality (using LabView) !!!! Fingers crossed!!!!!!!!!!!!

Hi Deano,

Implementing this kind of funcitonality in LabVIEW should be relatively straight forward. I've had a look at the link that Richard posted, and it looks like you need a combination of the logic gates used (all of which are available in LV), and the use of shift registers for feedback. have you much experience of using shift registers? If not, have a good look through the help files.

Let me know how much experience you have of using these, and if need be I can knock up a small example for you.

Best wishes
