Purpose: Creates a Nyquist plot of the frequency response of a specified transfer function.
Installation: Download Nyquist Plot.opx file, then drag and drop it onto the Origin workspace.
Options:
Frequency: Frequencies at which to compute the response, specified as the following:
- Points: Number of frequency points to use for evaluating and plotting the frequency response
- Start: The start frequency of a frequency range for the positive frequency branch.
- End: The end frequency of a frequency range for the positive frequency branch.
Note that the negative frequency branch will be obtained by symmetry.
Numerator: Numerator coefficients of the transfer function
Denominator: Denominator coefficients of the transfer function
Output: The range of output data for plotting
