Manasa assisted a student from Hofstra University in Hempstead with a probability problem involving the Laplace distribution. The lesson covered calculating its mean, applying a reverse level shift, and plotting a cost function. They discussed how to set up the integrals for numerical evaluation in MATLAB and how to find the optimal reserve level by differentiating the cost function. Manasa will send the learner the derivation of the equation to find the optimal reserve level.

An instructor assisted a student from San Francisco State University in reviewing op-amp circuits, including inverting, non-inverting, and differential amplifiers, using slides from weeks 4 and 5. They worked through examples, applying KCL to analyze circuits and calculate gain, and discussed ideal versus non-ideal op-amp characteristics. The learner plans to review the textbook chapter on op-amps and will send the instructor the homework if they encounter difficulties.

A student from San Francisco State University, with assistance from a peer, reviewed MOSFET circuits, transistor characteristics, and small signal models in preparation for an upcoming exam. They worked through practice problems, focusing on conceptual understanding and problem-solving techniques. The student will practice small signal analysis and review textbook chapters before the exam.

A student, who resides in Salinas, reviewed small-signal modeling and analysis of MOSFET amplifiers, with a particular focus on common source configurations. The learner practiced converting circuits to their small-signal equivalents and calculating voltage gain. They were assigned practice problems from chapters 4, 5, and 6 and were advised to review past exams to prepare for the upcoming test, with review sessions scheduled for Saturday and Monday.

In a recent lesson, two students, both studying at New York University, worked through MOSFET circuit problems, focusing on calculating drain current (ID) using voltage division and various formulas. They reviewed homework problems and identified discrepancies between their calculated answers and the provided answer choices. One of the learners committed to reworking the unsolved problems and sending the solutions to the other, who will then seek clarification from their professor regarding the confusing questions.

A student from California State University, San Bernardino, reviewed MOSFET biasing, current sources, and current mirrors, focusing on circuit analysis techniques. The learner practiced solving problems related to finding resistor values and ensuring MOSFETs operate in saturation. They also discussed strategies for approaching exam questions and the importance of understanding underlying concepts.
