Laima 3 Objective: In this experiment we are going to learn about the function generator and oscilloscope. Then we are going to generate and measure Sine waves using the function generator and oscilloscope. By doing that we will be able to calculate the period of the waves and then calculate and measure the voltage across resistors connected to the function generator and oscilloscope. Proceduce: Firstly, we found the function generator in multisim, then set the frequency to 2Khz and selected the sine wave button. Then we found the Oscilloscope and set the coupling to GND, set vertical coupling to AC, Sec/Div to 250us and the volts/Div to 4V as instructed in the lab manual. After that we connected the positive point of the function generator to the positive point of the oscilloscope, and negative point of the function generator to the negative point of the oscilloscope on multisim. Then, we ran the stimulation and it started showing a wave form. After that, we selected one complete cycle of the wave form to determine the period of the waveform. Then we calculated each period and frequency of the table in the lab manual by changing the frequency in the function generator to 15khz, 70khz, 150khz and 500khz. Secondly, we connected another circuit on multisim. For this one we removed the oscilloscope and added two new resistors (R1: 220-ohm and R2: 47-ohm). After that, we measured the total voltage and voltages across the two resistors. Finally we calculated the Vtotal, V1, and V2 to see if the measured and calculated voltage is the same.

Calculations: R1 + R2 (resistance) = 220 + 47 = 267

Laima 6 R1 voltage = 220/267 * 4 = 3.29V R2 voltage = 47/267 * 4 = 0.704V R1 + R2 (Voltage) = 3.39V + .704V = 3.994V

Conclusion: 2 cycles = 6.8/Div 1 cycle = 3.4/Div - SEC/DIV = 10 us/Div 10 us/Div = 10,000 us/Div Period = 10,000 * 3.4 = 34,000 us Frequency = 1/34,000 us = 2.941 Khz - SEC/DIV = 5 us/Div Period = 5 * 3.4 = 17 us Frequency = 1/17 us = 5.8Khz - SEC/DIV = 5 ms/Div 5 ms = 5000 us/Div Period = 5000 * 3.4 us = 17000 us Frequency = 1/17000 us = 5.8Khz
