NOTATION CHANGE: Notation-Revised Table 4.1 of Fourier Transform Properties : Notation-Revised Table 4.1 . I removed the j factor notation in how the Fourier Transform is written in the text. The authors attempt to draw upon what you learned in ECE202, viewing the Fourier Transform as the Laplace Transform X(s) evaluated along the imaginary axis s=j w . As we'll discuss in class, this can be confusing. I will attach the revised table to each exam.
