Appendix C: User-defined Filter File Format
Pressing Custom in either the low pass, high pass, or
weighting filters section enables you to upload a
user- defined filter file via the File Manager.
The available user- defined filter types are Infinite Impulse
Response (IIR) and Finite Impulse Response (FIR). You need
to specify the coefficients or sections as well as group delay
for the respective filter type. Use the following examples to
configure the filter file format. The file is saved in the *.juf
format.
Example of the FIR filter file format:
#Type: FIR
#Delay: 10
#Coefficients: [0.001, 0.002, 0.003, 0.004, 0.005]
The coefficients of the FIR filter are described as follows.
0.001 //A[0]
0.002 //A[1]
0.003 //A[2]
0.004 //A[3]
0.005 //A[4]
NOTE
The FIR filter transfer function, H(z), is defined as:
H(z) = A[0] + A[1]z
–1
+ A[2]z
–2
+ A[3]z
–3
+ ...
where z = complex variable
