Hello, and apologies in advance if this question has already been answered on this forum.
I have a question about the tpic8101 automotive knock sensor interface device.
The center frequency of the bandpass filter is programmable, however I do not see commands to set the width of the bandpass filter.
How is this set, or what default value does it use?
For example, if I set the center frequency to 6kHz, does the filter capture 5.5 to 6.5 kHz? Or a narrower or wider band pass?
Thanks in advance-
MW
