Question

The theoretical phase ori can be calculated using tand(iiCR)e ? 7 Using this equation and the measured phase from step B.5, calculate the actual value of your capacitor, we are using 20% tolerance capac itors, so any deviation beyond 21% should be discussed with your TA before moving on. Caleulated Capacitance C-ek Percent deviation 6 % Part C. Measuring the magnitude response of an RC filter 1. You should still have the circuit of Figure 4 built on the breadboard. For this portion of the lab you will input differen: frequencies and measure the response. C 10 nF 2. Double check that the function generator's output is in High-aby pressing. Lilin Output Seup change Load to Hligh Z Done Figure 4 3. Use an oscilloscope probe to measure the output voltage on Channel 2 4. Use the measure function on the oscilloscope to measure: . Channel 1: Peak to Peak voltage .Channel 1: Frequency Channel 2: Peak to peak voltage 5. Adjust the input voltage until Channel 1 measures 10 Vpk pk signal, and complete Table 4 l'able 4: Magnitude Response of Figure 4 Input Frequency (Hz) Output Peak-Peak Voltage (V) 100 2 2. 3000 10E3 30E3 100E3 300E3 I E6 600 m

Explanation / Answer

open MATLAB then go to command window and type the following commands to create vectors

>> FrequencyVector=[100,300,1000,3000,10e3,30e3,100e3,300e3,1e6] % create ferquency vector

>> OutputVoltageVector=[6.2,10.5,10.3,8.2,3.8,1.8,1.0,0.6,0.6] % create output voltage vector

>> semilogx(FrequencyVector,OutputVoltageVector) %run given command
