Setting the phase matching options so that at 1 rads the phase is near 750 degrees yields the second bode plot. You can also use the bode plotter to measure a signals voltage gain or phase shift to place the instrument, click the bode plotter button in the instruments toolbar and click to place its icon on the workspace. The watertank system block represents the plant in this control system and includes all of the system nonlinearities to specify the portion of the model to linearize, first open the linearization tab. The bode plotter produces a graph of a circuits frequency response and is most useful for analyzing filter circuits. Would you please help me how can i work with ac sweep function of this. The first bode plot has a phase of 45 degrees at a frequency of 1 rads. The plot in hertz for a discretetime system with the ztransform variable in radianssecond.
Multisim live is a free, online circuit simulator that includes spice software, which lets you create, learn and share circuits and electronics online. For continuoustime systems, the same result can be obtained by scaling the laplace variable. Drawing bode plots the last bode plot you will ever make. Bode plotter the bode plotter produces a graph of a circuits frequency response and is most useful for analyzing filter circuits. Obtain the bode plot with frequency in hertz, when the laplace variable is in radianssecond. Another alternative is that you can use these notes to prepare bode plots of any function merely by using that function, adjusting the scale factors for frequency and the coefficient in the margin response. Stay connected to your students with prezi video, now in microsoft teams. The plot displays the magnitude in db and phase in degrees of the system response as a function of frequency. Multisim professional edition help 372061l01 national. Hi i have bulid low and high pass filter in multisim and i would like to make bode plot in labview to demonstarte the functionality of these filters an interactive session for student to let them for example finding threshold voltage using bode plot garph i use multisim connectivity ver 1 to connect multisim to labview. Bode plotter multisim help national instruments support.
Multisim by national instruments corporation is a wellknown piece of software that allows users to design and analyze electronic circuits. Bode plot of frequency response, or magnitude and phase. Install ni academic software for mac os x and linux national. Explore and understand common electronic circuits with multisim circuit explorer.
