For our fourth experiment in Electronics Lab I, we had to set up resistor capacitor circuits using a capacitor and a resistor. Objectives The objective in the lab was to measure the time constants of typical RC circuits and study the correlation between time constants and frequency response, using the oscilloscope as a measuring device. Procedures First, we had to connect a 1k resistor in parallel with a 1 milli farad capacitor using as an input a 0 to 3 V square wave from the function generator at a frequency of 100 Hz. Also, set the oscilloscope to trigger externally from the function generator at a sweep speed of 1 ms/division and set both channels at 1 V/division dc placing both scope probes on the input to the circuit. Then, take one of the scope probes and place it on the output of the circuit and increase the

Unformatted text preview: sweep speed to 0.2 ms/division. Next, you we had to return the sweep speed of the oscilloscope back to 1 ms/divison and change the frequency of the function generator to 500 Hz. For the next figure, we had to connect the circuit as before with a 1k resistor and a 1 milli farad capacitor, except switching the position of the two. As we did before, we had to repeat the measurement of the new circuit just created. After all the data is collected from the new circuit, we had to go back to the original circuit from the beginning of the procedure except replacing the square wave input with a 3-V p-p sine-wave input. We had to examine the two scope probes and slowly increase the input frequency from 50 to 500 Hz. Again, we had to switch back to the second circuit used in the procedure and repeat the frequency measurements. Analysis Conclusion...
