DELTA AND ADAPTIVE DELTA MODULATION AND DEMODULATION

Delta and Adaptive delta modulation and demodulation trainer kit.

Technical specifications:

·        500 Hz and 1KHz sine wave message signal with variable amplitude.

·        Selectable clock frequencies from 8KHz to 128KHz.

·        Individual test points for each and every block for easy understanding the concept.

·        2mm Banana patch chords and sockets for easy connections.

·        Waveforms are just like Book theory so easy to understand the concept.

Hi everybody,
                      I an doing an DDS function generator AD9833 IC based. I want it to interface with 89s52 or equivalent. The frequency and waveform should display on 16x2 LCD. If anybody knows about this and source code please share it with me.It will be very helpful for me.

It is done by 89s52 microcontroller .If anybody wants this code and circuit please add comment...

Introduction

I am a telecommunication engineer.I am very much interested in analog and digital circuit design and development.I have developed many types of trainer kits which is very helpful for engineering and polytechnic students for E&C domain.

 

Students having different ideas are always welcome.....
