Hello everybody!

It's high time to finish my project. Today, my teacher has seen my project and therefore I would like to make some  summation of my work.

The objective of my project was creating signal generator. At the beginning of my work I had some assumptions - principle of operation, range of generated frequency ...... and other parameters were assumed by me.

Now I can compare final results with this assumptions and comment it.

I think that the most relevant issue is that this device works correctly - is able to generate three signals and I can wireless control it. In my opinion this is some kind of success. Of course, there are also drawbacks, but about them I will write later .

From  electronics point of view all were performed well, because all working. The main problems were connected with quality of generated signals - PWM is frequency non-stable. SAW signal has low maximum frequency. And the sine signal. In sine signal case I have a lot of remarks.

First off all - frequency characteristics - real frequency characteristics are other than simulated, because I have not  used accurate pasive elements - resistors and capacitors. This is main reason different characteristics.
In addition for low frequency signal has flat shape on top. So, I am convince that this issues need more attention - remark for future for young constructors.

Next problem... I did not have enough time, but I made one mistake. Devices such as signal generator require frequency characteristics and comparison real frequency characteristic with simulated. I should have done it. This is very important from using point of view. 

So... I think that this conclusions are satisfied your expectations. Time to say goodbye!
