INTERNAL FILTER RESPONSE
The Y filter supports several different frequency responses, including two low-pass responses, two notch responses, an extended (SSAF)
response, a CIF response, and a QCIF response. The UV filter supports several different frequency responses, including four low-pass
responses, a CIF response, and a QCIF response that are shown in Table 10 and Table 11 and Figure 6 to Figure 18.
