ABSTRACT: The purpose of this project is to develop and implement an application that simulates an FM System using C# Programming Language. The application works as a visual aid, and gives the ability to generate three types of input signals with ability to control their parameters (Frequency and Amplitude). The application can also generate a carrier signal ranged at the FM standard band of frequencies (88 to 108 MHz). The main task of the application arises when frequency modulate the carrier signal with respect to the message signal which is already generated (three types). Then, the modulated signal is transmitted over a channel and affected by channel noise–where the user can vary its parameters-.Detecting and recovering the message signal at the receiver end is also a possible process in the application. All the generated signals and the modifications applied to them are displayed on dedicated windows.

ABSTRACT :Phase shifters are four-port microwave devices which take an input signal and output in phase and shifted phase version of the original signal. These devices can be used in phased antenna arrays, balanced mixer, and Amplifier. The goal of this work is to construct a hybrid coupler phase shifter which will provide a 90 degree phase shift to a signal with a center frequency of 2 GHz over a 200 MHz bandwidth.

What made this project exceptional is the hybrid coupler phase shifter has not been extensively studied. Some papers have provided rough guidelines for constructing these shifters, but there is little exploration of performance.

This work uses AWR as a simulation tool to provide design analysis, and experimental work was performed in the RF laboratory at the Arab International University “AIU
