These are both very basic questions from a beginner, so be kind! 😀
1) What is the frequency of DV voltage ripple? Is there such a thing? I was reading about half and full wave rectifiers and voltage regulators.
2) If a signal generator produces a sine wave at a specific frequency, is it simulating an AC supply? I don't want to mess with mains supply, so could I use a signal generator as a safer option to experiment with half wave rectifiers, for example? I don't trust myself enough yet!

I don't know what you mean by DV voltage ripple. When a power line frequency is rectified it is not flat there is some ripple left over from the line frequency. Down stream capacitors/inductors are added to reduce ripple. If that is what you were asking.
Your second question it yes it is a supply or a source. Just may not be as high as the line voltage or have the same frequency as line voltage or the same power delivery potential as your power line so its safe.Normally if your using a function generator it is low power and safe.
Your right though if you have projects using line power then you have to make sure your using componants that are designed to isolate the line to one side of your circuit so that it's safe. I have gotten shocked by line voltage when I was younger working in the military and it is something you don't want to make a habit of.
