ساعدوني في مشروع التخرج الله يساعدكم

السلام عليكم

I have in this summer my senior design project,it is a simple wireless communication link

It consists of two parts: Transmitter and Recevier

The system should do the follwing:

1) Converting the input signal (analogue) to digital using 8-bit A/D converter

2)then take the output of the conveter and transmit it thru a simple antenna

3) receive the signal thru another simple antanna

4) Convert the received signal to analogue signal

Now, me Question is ithat is there any component has to be added to the system beside the components i mentioned?

and

I am using ZN427 as my A/D converter but there are some pins i dont understand what to put in them.

SO,PLEASE HELP ME, THE IS LIMITED.
