Abstract AR
في هذا البحث تم تصميم و بناء منظومة اتصال فديوي ضوئي باستخدام تقنية تضمين التردد النبضي في هذه المنظومة تولد النبضات في مرحلة الاستلام يتم توليد نبضات بتردد مضاعف إلى تردد النبضات المرسلة لعملية فك التضمين باستخدام مرشح الترددات الواطئة و قد أمكن الحصول على نتائج بعرض حزمة نقل ضيقة جدا (25ns) و حساسية استلام عالية باستخدام تقنية مضاعفة التردد.
Abstract EN
An optical video communication system is designed and constructed using pulse frequency modulation (PFM) technique.
In this work PFM pulses are generated at the transmitter using voltage control oscillator (VCO) of width 50 ns for each pulse.
Double frequency, equal width and narrow pulses are produced in the receiver be for demodulation.
The use of the frequency doubling technique in such a system results in a narrow transmission bandwidth (25 ns) and high receiver sensitivity.
