If sys is a multiinput, multioutput mimo model, then bode. This circuit presents a common emmitter amplifier circuit built with an npn biplolar junction transistor bjt. Bode plots are a very useful way to represent the gain and phase of a system as a function of frequency. For continuoustime systems, the same result can be obtained by scaling the laplace variable. The bode plot is a graphical representation of a linear, timeinvariant system transfer function. How to use the oscilloscope and function generator in electronic workbench tagalog version duration. Comparison of bode plots using smartctrl for validation purposes, it is also interesting to measure the bode plot of the open loop gain using psim. The plot displays the magnitude in db and phase in degrees of the system response as a function of frequency.
To do so, in the simulink window, in the apps gallery, click linearization manager to specify an analysis point for a signal, click the signal in the model.

Electronic engeneering hf and software 10,077 views. This is referred to as the frequency domain behavior of a system. It is usually a combination of a bode magnitude plot, expressing the magnitude usually in decibels of the frequency response, and a bode phase plot, expressing the phase shift. Obtain the bode plot with frequency in hertz, when the laplace variable is in radianssecond. Figura 1 a icone bode plotter b ligando a um circuito c instrumento aberto apos iniciar simulacao e clicar em reverse. Then choose a db probe from the pspice menu item pspice. It uses the expresion plotter to calculate the gain of the frequency response. Bode diagram design is an interactive graphical method of modifying a compensator to achieve a specific openloop response loop shaping. Here you can create your own examples with the bode plot online plotter. A bode diagram is a graphical representation used to characterize the frequency response of a system.
The mydaq instruments in multisim allow you to compare a schematically captured circuit with a prototype of the same design. Getting bode plot for a circuit in simulink matlab. The software adds the linearized model, linsys1, to the linear analysis workspace and generates a bode plot for the model. In electrical engineering and control theory, a bode plot.
