Hi,I am PhD student.now-a-days,I am working on transmission of digitized signal(Millimeter wave) over fiber.My query is about the possibility of analog to digital conversion on the transmitter side without using matlab component and similarly on the receiver side,the back conversion to analog again.In a one line”ADC and DAC without using matlab component”.I look forward for healthy discussion.

Regards,
Saqlain

    there are built in component that can do this conversion, you do not need to write your own matlab code.
    they are called
    “Analog to Digital”

    “Digital to Analog”

    hope that helps,
    thanks

    Thank you Mohammed A.A for reply.Actually,i have Optisystem 7.0,and there is no such components like ADC and DAC.can you please tell me which version of optisystem has “ADC and DAC components” and can we get it for free?.I would be happy to listen from you again.

    It is OptiSystem 15,
    you can use the trial version for one month for free.

    best of luck

    Dear Mohamed A. A. Abouseif,i hope you are doing well.I downloaded the optisystem 15 trial version but could not find the ADC and DAC components.Can you guide me where i can find “ADC and DAC” in components library.
    Looking forward to listen from you.

    Dear Muhammad,
    they are called digital to analog and analog to digital in the evaluation version.

    thanks

    Ok let me check it.Thanks

    dear Mr.Mohamed A. A. Abouseif and Mr. Muhammad saqlain,
    can you explain to me about how to use the analog to digital / digital to analog tools? i mean, do you just connect it from the electrical signal source or it has to connect to other component first or something like that?
    im working on my final project about digitized rof. your answers might help me so much.
    thanks

    Dear Zulfiqar,i still have not started work on digitization.I will start simulation in few days and will be in better position to explain you the use of ADC and DAC components in simulation.

    Also, there are two examples of using ADC and DAC.
    DP-16 QAM example with ADC.osc
    DP-16 QAM example with DAC.osc

    these two examples might help!!

    thanks

    Thanks a lot to all of u sir. I will try with the examples and hope it will work.
    Good luck to both of you too!!
