regarding the maximum allowable group delay, my customer requires 1.1ms of group delay at 15Hz.
This derives from this requirement: he would like to replace an old electro-mechanical gyro with a ferquency response equal to a single pole RC filter, with cut-off frequency at 150Hz. The bandwidth of interest is around 15Hz, so He requires that the new gyro (your sensor + filters) has a similare frequency response, or better.
If I would like to measure the impulse response of the system (gyro + filters), can I use the self test funcion?
Can I force the test pulse at t0 and read the gyro output to plot impulse response?
Test pulse is applied exactly when I deassert the CS signal?
Thank you in advance and best regards,
