interpolating
10.6 FIR filters
The DAC1205D650 integrates three selectable Finite Impulse Response (FIR) filters
which enable the device to use interpolation rates of 2
×
, 4
×
or 8
×
.
All three interpolation filters have a stop-band attenuation of at least 80 dBc and a
pass-band ripple of less than 0.0005 dB.
The coefficients of the interpolation filters are given in
Table 33 “Interpolation filter
coefficients”
.
