Basic Digital Operation (Option 651/652/654)Using Finite Impulse Response (FIR) Filters in the Dual ARB Real-Time Modulation FilterDuplicating the First 16 Coefficients Using Mirror TableIn a windowed sinc function filter, the second half of the coefficients are identical to the first half inreverse order. The signal generator provides a mirror table function that automatically duplicates theexisting coefficient values in the reverse order.1. Press Mirror Table. The last 16 coefficients (16 through 31) are automatically generated and thefirst of these coefficients (number 16) highlights, as shown in Figure 8- 19 on page 210.Figure 8-19FIR table coefficientvalues, may be from thefactory default values orentered by the user.For details on each key, use key help as described on page 42.Use the Goto Rowmenu to move aroundand make changes tothe FIR Valuescoefficient table.210 Agilent N5161A/62A/81A/82A/83A MXG Signal Generators User’s Guide
