Is it possible to recognise and record the amplitude values from a signal??
显示 更早的评论
Is there any function in MATLAB code or a block in Simulink which could recognise and display the amplitude values of a signal?

Would this just be like directing the signal to a scope? Signals in Simulink basically _are_ just amplitude values (with some timing information attached.)

Can you be more specific Mr.Lakshman? Do you know the signal which you give as an input... and do u want to implement it in MATLAB or simulink?

That sounds sort of like a Buffer Block.
Or perhaps what you want is Data Logging? http://www.mathworks.com/help/toolbox/physmod/simscape/ug/bsgpq8n.html

Data Logging is to display the data. But Mr.lakshman wants to record and feed the same data as input. Can that be done using Data Logging?

I am not certain. I have read some postings about Data Logging in passing, but I have never worked with it myself. I have had the _impression_ that logged data can be recalled and used later, in some configurations.
Perhaps would would be appropriate would be something like using a triggered subsystem around a buffer. Or is that not suitable for analog signals? On the other hand, the bit about "recognizing" the signals is hinting to me that if an analog signal is fed in, then an A/D convertor-equivalent to "read" the signal would be suitable; the then-digital signal could be buffered.
