The term project involves the practical application of frequency modulation (FM) in transmitting images of limited size (typically one LOGO).
Step 1: Text-to-speech conversion (Ardinuio, etc.)
Step 2: Modulate in FM and transmit
Step 3: Receive and Demodulate
Step 4: Filter out and detect.
Step 5: Speech to text conversion
Step 6: Prompt on an LCD screen
How can I design this project ? I understand nothing please suggest books, project like this

Because the scope of what you are describing is so advanced I am sharing a completed project.

SDR radio branched off into LimeSDR
Because image is a subset of Video.
High definition video has very good quality images and sufficient documentation.
LimeSDR has made conciderable progress. When the package installs and is up and running it has merit as a successful project.

FM modulation as a basic kit of analog signal, it uses a microphone is demonstrated. which is not enough to send nice images.

Nice images can be sent with an ESP32 digital camera,
Licensed amatuer radio operators have been sending HD images hundreds of miles.

You will convert the image (such as a university logo) into a sound signal using a software program. Then you will convert the sound back into an image with FM receiver and transmitter circuits. You will try to obtain an image similar to the initial image. Prof says that

Welcome to AAC.

AAC rules limit assistance for coursework to guidance and direction based on your own attempts at a solution. You will need to explain what you have tried and why you think it doesn't in order work to get help.

If you have no idea where to start, you will need to talk to your professor, or a TA, or some other resource provided by your school. Once you actually begin to solve the problem, you can explain what you are trying to do and what trouble you are having.

Good luck with your project.

Few days ago I had a similar project related to AM modulation transmitter and receiver and I found a video where a guy was making circuit for that and he try that with NE555 IC but made a simple FM circuit. I am pasting link here

Video Link

But do keep in mind doing such projects with discrete components can be very challenging as I face my self because inductors and capacitors combinations behave differently on different frequencies I would recommend you to do this project on microcontroller I did my AM modulation on STM32F407VGTx and it worked fine
