hi to all,
maybe someone can help me. i have converted the analog mpx (fm) signal from a common radio chip into a digital signal with a ADC. now, i want to demodulate the RDS data from the fm baseband signal on my FPGA. first i reduce the bandwith to 57 KHz (which is the carrier signal) and after that i will try to demodulate the digital RDS data out of that signal. i would generate all this in VHDL. which filter should i use for this, FIR or IIR? does anybody have an idea which components i need additionally. i'm not really a VHDL guru but i try to working on it.
thanks a lot.
