AM/FM DSP Implementation

[agha]

Hi
I want to use digital techniq to implement AM/FM modem for a transceiver. Now I need some help about it such as the best scheme for designing or ADC, DAC and DSP selection. The IF signal is 1.4MHz. Another import thing is the MIPS that these modulations/demodulations need.
Thank you. Agha

Hi Agha
You can use the DDC to create I and Q component from samples and process them for Am and Fm Demodulation. These processes are standard and exist in many books.

Hi
I know How is the best method to implement but I try to find a prepared code for these; VHDL or C

it is easy to implement it using fpga,which has much flexible.
