Filter Capacitors Key To Portable Designs

Back 20 years or so "Filter Caps" were used to compensate for the RF Wave front of activity in digital circuits.

So what is new here???

I mean has digital wave forms progressed that Rf knowing is not necessary anymore.

I Dun Know about this one, but it seems the wheel is being invented just one more time again?????

It is always a new thing to newly born what has been known to others for ages. Let them enjoy their first rain. After all learning process starts somewhere and it can be fun again and again. Everything is not meant for experts.

........what a breakthrough.........I thought it was basic function of a filter capacitor.....or am i wrong , and anolg and digital circuits seperations are difficult in what sense??????? is it easy or difficult to reinvent wheel............

Where is the charge stored in a capacitor? Plates or dielectric? When you separate the plates farther and fill more dielectric then capacitance comes down? Why? You have more dielectric inside the capacitor but why capacitance comes down? What makes capacitance inversely proportional to plate separation?

These are basic knowledge for those who start learning about capacitor in their high school class. You learn more about capacitors in your Ph.D. because capacitors are not perfect devices and they carry property of dielectric filled inside the capacitor. Then think of vacuum filled capacitors and locate the charge in that vacuum filled capacitor. If you want to think more then think about earth as capacitor and locate the second lead point for it in the universe wherever you like it.
