Is it possible to read data from a schematic using an antenna, and display the signal on the LCD of the Altera DE2 board. For example, I am making an electric field detector. May I display the strength of the signal on the LCD? If so, how is this possible?

Normally you would utilize an analog-to-digital converter to acquire the signal. But DE-2 doesn't have general purpose ADCs, only dedicated audio and video codecs.

Ah, ok thank you!!

As an additional remark: You achieve nearly everything with FPGAs. But their strong point is fast digital signal processing at speeds beyond multiple MBit/s and MS/s. Processing analog measurements of a few Hz bandwidth can be most easily done with a single chip microprocessor, e.g. a PIC.

So would an 8-bit PIC16F684 be suffice?

Basically yes. The program memory size should selected according to the intended application complexity.
