Introduction

Arbitrary waveform generators AWG : are sophisticated and complicated signal generators which allow the user to generate arbitrary waveforms within published limits of
. frequency range, accuracy and output level

6

Unlike traditional function generators, which are limited to a simple set of waveforms , An AWG allows the user to specify a source waveform in a variety of different ways such as exponential, cardiac, sinc function or the other
.combinations

7

Project objective
Generating multi signals with the option of changing frequency

8

Project idea

We will use the FPGA to implement the digital representation of the different signals, then we will turn them to the wanted analog signals using a digital to
. . analog converter
Note: all codes are VHDL code which is a
.suitable interface to deal with the FPGA

? Why using FPGA
The fact that FPGA can be easilyreprogrammed make it possible to get any desired waveform like exponential , cardiac and sinc wave form , we can also add or
.subtract two signals ,etc
.The low power dissipation
