Students must work independently on this assignment, NO COLLABORATION. Any detected cheating will result in an E for the course for all involved parties. You are free to use any books, notes, or computer programs to solve this. If you get a result from a computer or calculator program (i.e. to solve a system of equations), indicate the program used to obtain the result. Otherwise all work done to obtain the result should be clearly shown.A. Derive a set of equations that describe a complete set of node voltages or loop currents in the circuit below (1.5 points) – Be clear with labels!B. Use the set of equations to find Vo(0.5 points).C.

Students must work independently on this assignment, NO COLLABORATION. Any detected cheating will result in an E for the course for all involved parties. Hand in a hard copy of the circuit and tables from SPICE that clearly show the requested results (can print directly from SPICE or paste into another program and print). Email the SPICE circuit file used in the simulation to [email protected] 11/29/01 at 2pm. If you used a software package other than B2 SPICE, please indicate that in your email. Also make sure your name is somewhere on the email.Use SPICE to find the phasors for the steady-state response of vo(t), when fo= 100, 500, 1000, 5000, and 10000 Hz. The magnitudes should be linear (i.e not in dB) and phase should be in degrees.()V 2cos10 tfoπ1.59 kΩ0.1 µF+vo(t)-0.1 µF1 kΩ1.59
