CS代写 Problem 1: Related to Chapter 4 – cscodehelp代写

Problem 1: Related to Chapter 4
Marks are allocated for:
• Redrawing the diagram in your answer sheet and labeling voltages/currents.
• Writing the circuit equations, according to your diagram, WITHOUT SIMPLIFYING them.
• Solving to obtain correct solution.
You can simulate in PSPICE or LTSPICE to verify v_x value.
Problem 2: Related to Chapter 7 in Textbook. See Week07 and 08 Tutorials and Masterclasses. Also Week07 Weekly problems.
PART A: Related to Chapter 6 of Textbook (C and L)
PART B: Similar to M08 questions Marks are allocated for:
• Redrawing the diagram in your answer sheet and labeling voltages/currents.
• Writing the circuit equations, according to your diagram, WITHOUT SIMPLIFYING them.
• Solving to obtain correct solution.
Write KCL at –ve pin. Solve for v-.
Write KCL at +ve pin. Solve for v+.
Use Ideal op-amp assumptions. i+ = i- =0A and v+ = v- Equate v+ = v- and Solve to get vo = -5.35V
PART C: Similar to Week 10 Problems.
Minimum = 154 , Maximum can be found as illustrated in Masterclass in Week 11, page 10. See also Week 10 problems with solutions.
Problem 4 : Related to T6 Video Lectures PART A
This is discussed in T6 video lectures and slides. Students are expected to write 1-2 concise sentences for each of the components mentioned to describe their role in the circuit.
Hint: You can use PSPICE to help with your sketch and make sense of it.
This is the ripple waveform you are supposed to sketch at Point B. See T6 V11 video lecture and slides. PART D
See also lecture notes on RC and RL circuits. PART E
See Masterclass in week 11, page 3 for derivation (for half wave rectifier). Similarly for full wave rectifier, it can be derived.
Problem 5: Op-amp derivation question, which incorporates finding for a bridge circuit (see T4 V8 slide 10)
Two correct ways to solve are attached. See next 2 pages.
