Hey there, I am basically modulating a PCM interleaved data using digital technique(PSK, FSK) in LabVIEW. I have read about RNRZ where it is said that the bandwidth needed for it is only 0.7 of the data rate. Now I know that for modulating the bits, we need I/Q symbols, do I have to bandlimit the RNRZ data first or do I have to generate I/Q symbols and then apply filter?
Because bandpass filters involve higher effort, baseband filtering is usually preferred, e.g. in Gxxx (gauss shaped) modulation schemes. Both is possible, however.
