Perhaps you heard about Software Defined Radio, or SDR, which suggests that use digital devices in radio facilities as much as possible. But you still have to design some analog parts: RF front-end, and baseband signal amplifer.

Hi Cevitamic,
i agree with Whizkid's opinino.Analog demodulation schemes cannot be realized using an FPGA, and u need a FPAA for that.
you can realize any ASK/PSK/FSK or QAM (which is combination of ASK/PSK) through an FPGA for an SDR module. But AM/FM are purely analog modulation schemes, so even if u use a front end ADC, its not possible to implement the receiver in an FPGA.
Hi David,
If u r planning to make an ASK/FSK/PSK then FPGA is a good target device for that.you can easily implement those in a xilinx fpga using simulink blocksets, with the availability of a new tool called "System Generator"

it is easy to implement it with FPGAs!
bibo1978 said:I believe FM data extraction can be done in digital, several techniques can be used.
But in general you will need a front end reciever "amplifier, mixer and a PLL" to downconversion process afterwards you may extract data with appropriate technique for example if you have a large fc/B ratio you may only use a limiter rather than using a ADC, yet what I am asking if it is economicaly acceptable to do an FM reciever on FPGA ?
