as a matter of fact i never missed classes. i am currently a 3.0 gpa holder.
i know the 1st transistor is used for biasing, and the 10k resistor is used for negative feedback.
i only merely asked because i wanted an enhancement of my knowledge, as my teacher would be taking a thorough demo of this project so thought i should revise in detail each step of the circuit.
i made this, and it works fine.
checked the output on a CRO as well, and even implemented it on the software Multisim.
