The number of mentions indicates the total number of mentions that we've tracked plus the number of user suggested alternatives.
Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Digital Loop Filter for Digital PLL Design
Are you interested in an all-digital solution? If so, I have a couple of digital PLL's you might want to check out. These are the PLL's I use if I want to demodulate a digital signal in hardware, as demonstrated by this example. If what you are looking for is a mixed digital/analog solution, then ... I don't have an example.

Can you explain remez exchange algorithm with example?
My interpolation tutorial has a section of generating interpolation filters using the Remez Exchange algorithm. It starts at about page 39, and has some nice pictures to help illustrate the concept. It's a bit of a different approach from the standard Parks-McClellan approach to Remez, since the tutorial shows the design of an M-band filter rather than a generic lowpass. This puts additional constraints on the filter design, to the point where the Parks-McClellan approximations don't necessarily make sense any more. In other words--it's strictly Remez.
