(C) Perform the same analysis as in Task 4A but remove the capacitor from the circuit so that the circuit consists of the inductor in series with the resistor. Congratulation, the first digital simulation is done Figure 1 - Qucs main window A truth table is not the only digital simulation that Qucs can perform. Now the truth table of a two-port AND cell is shown. Place the diagram truth table on it and insert the variable Output. (B) Perform the same analysis as in Task 4A but remove the inductor from the circuit so that the circuit consists of the capacitor in series with the resistor. After performing the simulation, the data display page opens. I agree with you, focus on the function that creates the output image/pdf is move important than how the command line looks like. Also analyse how the phase of Vr varies as a function of frequency? Describe why the amplitude and phase of VR varies as it does. (A) Analyse what filter function is performed by the series RLC circuit by analysing what frequencies are present over R with an amplitude close to the source amplitude. In the example left Vout_phase is a variable that can be plotted in QUCS and it is the phase of the voltage Vout. Vout_phase=phase(Vout.v) Using the insert equation function in QUCS you can determine the phase of a current or voltage. Using the insert equation function in QUCS you can also find the phase of the voltage VR by using the command phase(Vr). To analyse how Vr varies as a function of frequency it can be illustrative to use combinations of linear or logarithmic scales on the x and y-axis of the plots. Once the simulation is run, it displays an output similar to what you would. 47 nF 10 mH + 1 VAC ~ R=502|| After the AC simulation is finished, plot the voltage over the resistor (VR) as a function of frequency. In the task you should analyse how the sinusoidal voltage (amplitude and phase) over the resistor changes with the frequency of the voltage source. The circuit has a sinusoidal voltage source with an amplitude of 1 V. Circuit stimulator that does not have a graphical user interface, Qucs are just circuits in one stimulator and are the stimulators for those circuits. AC voltage over resistor in RLC series circuit Perform an AC simulation from 1 Hz to 100 kHz of the circuit containing a resistor R, inductor Land capacitor C in series.
