در این پست می خوام در مورد سه مفهوم مهم در علوم مهندسی و علوم پایه، نمی توانم مرزی را بین علوم مهندسی و علوم پایه در این زمینه قایل شوم، صحبت کنم. همه چیز با فلسفه شروع کرد، که فکر کردن و منطق را برای بشریت به ارمغان آورد، بعد از آن فلسفه جوابگوی نیاز بشر نبود، علم ریاضیات نتیجه وادامه راه فلسفه بود.ما باید به ریاضیات به چشم ابزار فکر کردن نگاه کنیم. فرض می کنیم این ابزار از قبلا همیشه مهیا بوده و در اخیتار ما می باشد.

In optisystem i had problem in destructive interference coupler so i  created a thread in opicwave forum, i perfer share this problem here.







So we in this thread can find solution i share it here. if you set coupler to conjugate by changing phase shift to -90, it runs destructive interference in optisystem.If you set coupler to no conjugate with 90 degree it run destructive interference. I share file example here.

Yet i work on DVB-T in HackRF one, in TX we can send DVB-T and we receive it with a hardware dongle DVB-T. but for receiving with SDR Based we had error: see this link for our older work or this link.
