Phase margin is a measure of the distance from the measured phase to a phase shift of -180°.

This is commonly referred to as the “crossover frequency”. Figure shows the circuit in Multisim with an oscilloscope display and Bode plotter.Phase margin is measured at the frequency where gain equals 0 dB. The purpose of this lab is to demonstrate how to use Multisim in order to produce Bode Plots via AC Analysis. Figure 2: Bode Plotter in Multisim Using the oscilloscope find Vout to fill in Table 1 below. Lab 2: Bandpass Filter and Frequency Response1 Objectives Get familiar with computer-based instruments. The cursor is set to the critical frequency on the Bode plotter so that. This plot will allow for a determination of the range of frequencies for which an op-amp circuit operates optimally. Students will make adjustments to external bias resistors to determine the relationship between gain and frequency in op-amp circuits. Then using Vout and Vin, which is given as 5, calculate the. Learn to use Multisim circuit simulation software. After the schematic design is captured, Multisim provides you with an interactive oscilloscope, bode plotter, logic analyzer, power supply, multimeter, function. I have designed the experiments around student familiarization with usage of specialized instruments such as the Bode Plotter, Spectrum Analyzer and Network.
