      Hi Nirmal, nice to meet you and thank you for your suggestion. I'm done with it. Could you please check if you can see the subtitles now? Thanks again for the reminder. :)😄

    You pointed the disadvantages of linear Hogge PD. Do you plan to do another video on disadvantages of Bang Bang PD based loop, especially how loop dynamics, Bandwidth, jitter transfer function etc vary non-linearly especially as a function of high input jitter (much more than intrinsic noise) such that we cannot linearize the BBPD.

      Thanks for the feedback. I've done it here: ua-cam.com/video/m_8uUu90af8/v-deo.html
      But, your point is good for the Bang Bang PD's loop dynamic and I'll make another video for it. :)

    Could you please upload video to talk about loop latency (limit cycles ) and how to improve BBPD hunting jitter in real CDR ??

      Thanks for the good idea. I'll do another loop latency (limit cycles) and how to improve BBPD hunting jitter.
