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

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.
