Using Finite Impulse Response (FIR) Filters in the Dual ARB Real-Time Modulation Filter
4. Continue entering the coefficient values from the table in step 1 until all 16 values have been
entered.
Duplicating the First 16 Coefficients Using Mirror Table
In a windowed sinc function filter, the second half of the coefficients are identical to the first half in
reverse order. The signal generator provides a mirror table function that automatically duplicates
the existing coefficient values in the reverse order.
1. Press Mirror Table. The last 16 coefficients (16 through 31) are automatically generated and
the first of these coefficients (number 16) highlights, as shown in Figure 8-19 on page 221.
