Requires time consuming graphical programming and no direct way to compare simulation results to testing results. VEE 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. Software Packages to Construct Bode Plots Software Reasons for using/not using a software package to make Bode Plots 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. Table 1 outlines the software packages that are traditionally used for such plots. The second of which is the phase of the complex transfer function in degrees versus frequency. It consists of two parts, the first of which is the complex transfer function in decibels versus frequency, where the function is the magnitude of the ratio between the output voltage and the input voltage. BACKGROUND Bode plots are a way of determining the characteristics of a filter. National Instruments Signal Express attempts to bridge this gap and provide a means of verifying proper implementation in time saving real-time testing. Often the last two parts involve time consuming graphical programming and tests which attempt to determine whether the final product is performing as was expected and seen in the simulation. Design involves determining the desired effects a filter is to perform on a signal, selecting the appropriate values for parts in the filter, simulating the filter, and testing the final design.
