Testing a final product and comparing the output to the desired simulation results is theįinal check for problems a real world device might exhibit that were not accounted for in the Requires time consuming graphical programming and no direct way to compare simulation results to testing results.ĮLVIS Bode Plotter Much simpler than LabView or VEE, however does not have a way to directly compare simulation with testing results.Īllows for 12 bit analog to digital conversion, easy setup and use, and a way for simulation results from Multisim SPICE to be directly compared to testing results, verifying the operation of the filter completely and easily. When attached to the oscilloscope, results in a less accurate result because the resolution provided by an 8 bit analog to digital converter is far less than the resolution provided by the 12 bit analog to digital converter.

LabView LabView requires time consuming graphical programming to acquire an inputted signal from the ELVIS Data Acquisition board to a format which can be compared to simulation results. Software Reasons for using/not using a software package to make Bode Plots Software Packages to Construct Bode Plots Tableġ outlines the software packages that are traditionally used for such plots. Second of which is the phase of the complex transfer function in degrees versus frequency. The first of which is the complex transfer function in decibels versus frequency, where theįunction is the magnitude of the ratio between the output voltage and the input voltage. This gap and provide a means of verifying proper implementation in time saving real-time testing.īode plots are a way of determining the characteristics of a filter. National Instruments Signal Express attempts to bridge Programming and tests which attempt to determine whether the final product is performing as Often the last two parts involve time consuming graphical Perform on a signal, selecting the appropriate values for parts in the filter, simulating the filter,Īnd testing the final design. Design involves determining the desired effects a filter is to
