How to generate Autocorrelation plots and PSD (Power spectral Density) for different PRBS2 and PRBS31 NRZ signals?

Hi, I am new to matlab and looking for Some example code to generate PRBS2 to PRBS31 binary NRZ sequences. With this Sequence i would like to plot Auto correlation and PSD of these diff signals and understand frequency contents of those random signals.
