Sir, Actually we have designed the integrator block in altair embed software, but we have not getting the correct results with respect to magnitude as compared with input to output.

Thanks in advance

    Hi Chinmaya,

     

    Can you send me your diagram ?? It would be easier to check.

     

    Regards,

    I have attached the integrator developed model. But it is giving me same magnitude only when the input magnitude is 1 volt.

    I do not see any problem with your digital integrator, here's a comparison with a continuous integrator

    Thank you for reply

    But actually it ranging from 0 to 3 but I wanted it to be from example -1 to 1 like that

    Hi Chinmaya,

     

    I'm not sure about your requirement . Try using Transfer function block and provide the denominator value to 1 0 and choose discrete on the dialog.

    Chinmaya,

    You are integrating a sin wave of the form 50sin(10*pi*t)

    The integral is (-50/(10*pi))cos(10*pi*t) + (5/pi which begins at 0 amplitude and peaks at 3.18 which is what you are seeing, I don't understand the question you are asking, can you further explain what you are trying to do or what you expect to see.

    Ric
