I have an experimental data as shown below. The data was provided in Magnitude and Phase format. The magnitude (Accelerance) is in g/N and Phase is in degrees. I have been trying to convert this in to Complex Receptance data in m/N.
How can I convert this data in to Complex format (Real & Imaginary)?
