| To better investigate how the circuit operates we next need to break (open) the feedback loop and stop the circuit from oscillating. We can then inject a test signal at the base of the transistor as shown in figure 4. Add the modifications shown in figure 4 to your circuit. | To better investigate how the circuit operates we next need to break (open) the feedback loop and stop the circuit from oscillating.
