Spectrum of Manchester, Bipolar, Manchester diiferential line coding

Hello, guys, i have question how i can make spectrum in matlab Manchester, Bipolar, Manchester diiferential line coding.

How you can see Manchester is 4th signal, Differential Manchester is 7th signal and Bipolar is 9th signal.

Speed is 130 kbit/s.

Frequency is 130 kHz

Amplitude voltage is 1 V

How i can calculate or know the line band that will provide the transmission of the stream with signal power losses of less than 5%?
