DC#43 Power Spectral Density and Bandwidth of QASK / QAM signal || EC Academy

[@gateprep970]

Sir, as you told us QPSK is similar as of QASK (Talking about PSD). In QPSK why the frequency shifted to the carriier frequency fo. I am following your playlist as it is. I have a confusion or maybe misconception i think its our choice how we want to show PSD, i.e. seperately by shifting it by fo or show it as collectively with frequency fs ..Am i right? pls correct me if i am wrong
