Guidance needed to generate Pseudo-Random Binary Sequence (PRBS) and ternary-sequence signals

I want to generate PRBS and ternary sequence signals but I'm stuck. Can you guide me on how I can implement that? I have attached the sample image.

Please refer to the information and examples in these links:

https://www.mathworks.com/help/slcontrol/ug/prbs-input-signals.html

https://www.mathworks.com/help/slcontrol/ug/frest.prbs.html

input = frest.PRBS('Order',12,'NumPeriods',1,'Amplitude',0.05,'Ts',5e-6)

 
The PRBS input signal:
 
      Amplitude  : 0.05
      Ts         : 5e-06 (secs)
      Order      : 12
      NumPeriods : 1
      OneSamplePerClockPeriod (on/off)    : on
      UseWindow (on/off) : on
 

plot(input)
xlim([0 0.001]), ylim([-0.05 0.05]), grid on

Yes I have created these signal but i stuck in creating power spectrum density of that signal

Hi @MUHAMMAD AJMAL

That's great. I'm not a signal processing expert, but I believe the function pwelch() estimates Welch's power spectral density. You can check out an example in the following link: https://www.mathworks.com/help/signal/ref/pwelch.html

If Welch's power spectral density isn't what you're looking for, I recommend waiting for someone with expertise in signal processing to provide an answer.
