pattern matching

[psuresh_ece1985@yahoo.co.in]

how to do the pattern matching between two signal...and my requirements is if any h igher priority signal comes lower priority signal preemptive after finishing the H.P ,the L.P continue..how to do the task....plz reply..

Can you provide more details.  Not so bundled up..  An explanation of what it is that you are trying to achieve would help.

I'm trying to visualize what you are trying to do and it is not clear.

Do you want to match patterns between 2 signals?

Do you want to verify something with respect to a higher priority signal?

Do you want to detect and extract signals of different priorities?

What do you mean by "if any higher priority signal comes lower priority signal preemptive after finishing the H.P"?

What types of signals are you talking about?

etc..?

 actually i m doing the project in chimes (warning signal ) automation in car....we can assign the different priority for different warning signal.

i need pattern matching 

to detect and extract signals of different priorities and

want to verify something with respect to a higher priority signal.....

Okay..  The signal is actually a warning indicator of some sort (chime, buzz,ding, etc)

Can you describe the pattern or patterns that you are dealing with?  Is it different frequencies?  Message signal? What is it?

And how or what in the signal identifies a higher priority signal?  

Is it embedded in the signal?  Is it a message? What is it?

this is a  audio signal.... it  has ifferent frequenics (multi tone)....

 actually the pattern is store in predefined..and compare with file which is the higher priority....

You're going to have to spend some words describing your problem if you want a sensible reply.

You can use an FFT operation to turn a block of audio data into a measure of how much energy is in each frequency bin in that block.

You can use that spectrum to discern whether the audio contains a high chime, low chime, both chimes, buzz, whatever.

I agree with Steve.

My mind reading abilities have never been too good when it comes to figure out other people's needs..  Especially software.  😉
