- CONFIG_INTEL_DMIC_FIR_DECIMATE_BY_10¶
FIR decimate by 10
Type: bool
Help¶
This includes FIR coefficients to decimate by 10 into the build.
The high FIR decimation factors are needed for high microphone clock
rates due to max. decimation factor limitation of CIC. Also dual
FIFO configurations may need for one FIR decimation such high
decimation factor.
Direct dependencies¶
INTEL_DMIC && SOF
(Includes any dependencies from ifs and menus.)
Default¶
n
