For Part 1A) of the procedure, calculate the value of VOUT after 3RC from To . 2. For Part 1B) of the procedure, calculate the time for Vour to reach a value of SV from To. 3. For Part 1C) of the procedure, calculate the time for Vour to reach a value of 5V from To. 4. Design a network to achieve the Vour shown with the specified VN 0V 5V NETWORK 1ον 3 0.33 pF -20 ms-> 1.5ms To Fig 11-1 Input/output waveforms required for designing the network 11-1 5. For Part 3 of the Procedure, calcuilate the current value after 3 time constants from t 6. For Part 4 of the Procedure, sketch the voltage across the inductor in time relation with Vu to calculate the respective time HINT: To solve these Pre-Lab questions, it will be necessary constants, RC and L/R. Since R is a single resistor, it will be a series circuit with a resistor and a Cor L. Applying Thevenin's Theorem is the best wayto o achieve these required simplified circuits from To. Calculate the value of VL after 1 time constant from To. necessary to simplify the circuit to way to PROCEDURE: To achieve the 0 to 10V square wave from the Model 25 Wavetek Function Generator it will be necessary to adjust the DC offset and amplitude controls. 1.5K 1K Vout OUT 10 3K 25ms ー5ms Fig 11-2 Circuit for evaluating the RC circuit response A) Measure the value of Vour after 3RC (3 time constants) from To. B) Measure the time for VouT to reach 5V from To. C) Change C to 0.33 μ F, then measure the time for VOUT to reach 5V from To 2. Construct the circuit designed for Part 4 of the Pre-Lab.
