Okay , so here is my presentation about technical function design. I will talk about different components and s of system and how they react together. Okay , uh , first what is a remote control ? Simply it's a device , as you know , for uh , for sending some commands by some waves to uh another device to to tell different commands uh with this device. And the main idea we don't use any cable and we can rec react simpler with the device. Uh i it has different blocks , different blocks. Uh first is remote control have sh ha should have some electric circuits uh making interface with uh keyboard and uh r reading uh keyboard and reading the keyboard uh commands. And then inter then make uh these keyboard commands , uh in interpret these int uh keyboard commands. And then there should be uh an electronic circuit making uh electronic signals according to these commands and uh finally there is a transmitter which is a cord or a a diode making uh making uh waves to transmit through the air and uh uh this air this uh wave uh will be received by the by the other device like a television or whatever , to uh r to realise the command. Okay ,  uh about  what I found about uh different uh these different blocks are uh , usually there are two different methods uh to  for designing a remote control. They are based on infra-red uh waves or uh uh radio waves.
You still want me the presentation.
There are two different uh uh solutions I mean. This is uh this can be uh uh the the differences the th between different kind of waves , infra-red or radio waves. And uh also as uh I understood , and uh I think it was a part of uh Bob , uh uh presentation , people prefer to have uh to have uh the remote control with less button. So for the electronic part , working and interfacing , with button , we should we should try to t try to design a remote control having uh some some simpler buttons or some rolling buttons to just to just to search between different options , and showing o something on T_V_ and putting less lesser stuff on the uh on the remote control. And uh personal preferences , uh uh uh uh certainly a remote control with  uh working with radio waves is uh preferred because uh you can pr you can take it in any direction and you don't need to tune it any way. And uh uh again , using bigger buttons and less number of buttons are also preferred , as I see. Okay. That was my presentation.
Okay. I have a question.
