Earlier I didnt know what you meant by turning it on hard. But thinking about it a little further, did you mean that the current is actually flowing through the cap from +4.5 through Q2 (Emitter base) and through Q1 (base emitter), but there is only a very small amount of current becuse none of...
I don't have an oscope on me (poor college student), and I haven't simulated it yet. But wait if Q2 switches off wouldn't there still be the constant +4.5 volts on the other side of the capacitor from the voltage source canceling out the -4.5volt change?
Which direction is the base current in the PNP going? I'm still confused on that. Also, does the base current in Q1 sag because of the discharge versus charging rate? Man, I think I'm confusing myself way too much here.

You said earlier "If Q2 ever did turn off there would be a -4.5 volt transition at the base of Q1.". Could you explain why that would be the case? I noticed you guys talking a lot about feedback, but I don't see how that applies here. Could someone explain?
Edit: Ohhhhh is it because...

Yeah it sounds like a buzz with a 0.01u Cap, if you use a 10uF cap you can really slow it down and make it go to 1Hz (it does sound like pop). And thanks everyone for the posts, this is helping me think about this more!
@meBigGuy
From my understanding, right when the circuit is turned on, the capacitor is charging through the current from the sum of the resistances in series with the voltage source. Applying KCL at the node (in the attached diagram) you can see the current divides between the cap and the...
So I want to start off saying that I'm a senior in college in Electrical Engineering and I've been learning a lot about various kinds of circuits involving oscillators and I would like to know more about them. In school we talk a lot about them in various circuits and how important they are to...
Ok, I think I understand this now, so essentially the feedback loop is what the "current state" in the flip flop is, and the clock is the pulse that is sent into the other input terminals of both NOR gates which will change the state that is held in that feedback loop. Is that the way to look at...
Hello all,
I'm new to this forum, but I've browsed this forum quite a bit and it has helped me numerous times throughout my years of college. I have a question that I need clarification on with sequential circuits.
Synchronous Circuits store "information" using a clock and the added signal...
