Question and Problems: a. How does the RC stages affect theoscillator? RC stages affect the oscillatorin a way that it’s quantity make the frequency to be stable. The 180 degrees of the feedback network is the overall phase shift, and when using N RC stages, each RC section has 180/N degree phase shift. b. Why does it uses 3 RCstages? The frequency stability of only two RC sections is low when cascading process was done. On the other side, the three RC sections can provide a stable frequency when it’s cascaded because of its phase change rate that became high. c. What happens when the variable resistor R4 isadjusted? When R4 is adjusted, it is called the gain. The gain is the inverting amplifier which is the –Rf/Ri or in this circuit, -R4/R5. d. What is the total phase shift of the circuit?Explain. - Each RC stage have a 60 degree phase shift and the result is 180 degree and it’s on the RC sections. The another hand is the inverting amplifier and it also have a 180 degree phase shift so the total phase shift is the sum of this two and the total is 360 degree phase shift
e. Why is it essential to have a unity loop gain and a degree phaseshift? - It is necessary to have Av value that is equal to 29 because if we can get this gain value of the amplifier (A) to make the oscillations occurs in the circuit and this is by adjusting the R4 and R5. If the experiment that we made gain higher than 29 then the input signal becomes distorted and if we gain lower than 29 it can eliminated oscillation. We concluded that the unity loop gain and 360 degrees phase shift are essential to sustained the oscillation

Able to work under pressure. Research Oriented Skills REFLECTION: I have learned that patience and time is needed in learning new things. On top of that a good understanding and knowledge of circuits and electricity is required so that you can use it correctly to create circuits and being able to measure the resistance, voltage and current. The key idea of this is to learn from your mistakes. This will help me move towards my goal because I won't make the same mistakes that I made during this semester I will be able to apply the knowledge and skills I learned here in my nearby future.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
