# Connecting a RC circuit to the output channel of an astable multivibrator (follow up question)

Tinkering around, I found out that if I connect a capacitor to the load resistor, i.e. if I pass the output through a RC circuit, the voltage retains it original value, and the frequency too, if the capacitance of this capacitor is the same as the previous ones in the circuit. However, the square wave's upper edges are somewhat rounded, and somehow touch the V_init. Can someone give a possible explanation to this, as to how to apply Thevenin's theorem here, if it's actually feasible here, and how does this configuration relate to the initial circuit without a load resistor connected to the output?

• It's unclear what load resistor you are talking about and how you might connect the capacitor you talk about. Also, what is V_init??? What does "this configuration" actually mean and what is the initial circuit you mention? Aug 4, 2021 at 13:00
• @Andyaka you can check out my initial question, the link of which has been mentioned above. This is just a follow-up question. Aug 4, 2021 at 17:12
