The dualaxis option plots both magnitude and phase in the same plot, with the left axis the magnitude scale and the right axis the phase scale. How to plot reflection phase diagram of an ebg structure. The labview full and professional development systems include a basic fft power spectrum vi which can be used to create simple frequency domain plots from time domain data. Learn more about scope, simulation, simulink, communication, output, frequency, signal processing simulink. If you know the sampling rate, you can compute the corresponding frequency doemain, and then plot the phase versus frequency using the xy graph scope block. Using this frequency, the bode phase plot finds the phase of. At first i wondered whether they were using some clever method of estimating the frequency shift by actually measuring phase shift which can be done with appropriate data acquisition tools and software, avoiding the need for a full fourier transform type acquisition.
From the pspice menu, choose a phase probe pspicemarkersadvanced phase of voltage and place it on the same node. Run the simulation again, and voila we have a bode plot. Thus two sine waves differing in frequency by 200 hz get progressively out of phase with each other by 200 cycles every second. Run the simulation again, and the plot now shows the phase as a function of frequency.
Frequency is commonly measured in hertz, or cycles per second. Plotting amplitude versus frequency data in labview. How can i plot the phase difference between fields components. Set up an ac analysis to plot the frequency response both magnitude and phase of a circuit. How i can plot the magnitude and phase response oh the. They described the changes in frequency as phase shifts.
