J-DSP video examples

This web page includes video files (AVI) that demonstrate the J-DSP software in action. By viewing these AVI files the user can visualize how blocks are established and connected using a drag and drop process. There are are several simulation examples that are itemized below; their AVI (video) file and streaming video file are listed as a link. Both the AVI and the compressed (zipped) AVI are posted.



1. Export J-DSP simulations into MATLAB scripts
This video example illustrates a new script functionality in J-DSP. Specifically, it shows the process on how to export J-DSP simulations into MATLAB scripts.

اولا احب اشكر المهندس احمد بركه علي هذا المجهود العظيم الذي يقوم به حيث اني عضو جديد في هذا المنتدي الرائع
ثانيا ارجو منك يا بشمهندس مساعدتي فانا مطلوب مني تنفيذ
مش عارفcall flow of voip by sipprotocolby using (matlab)
وانا مش عارف اعمل الجزء الخاص بالmatlab واناواثق انك هتساعدني يا بشمهندس

شكرا جزيلا لك علىالرد الجميل
لكن للأسف خبرتى بالماتلاب بسيطة جدا
يا ريت تضع سؤالك فى موضوع منفصل بعنوان يوضح المشكلة و أن شاء الله تجد من يساعدك بأن الله
أعذرنى و بالتوفيق أن شاء الله
