Measurement loop and motion loop, Kalman filter has two different processes, measurement value update and motion value update.
This is the same as the positioning scenario, where we get a measurement and start moving. Here the maximum value varies, but the principle
Still the same.
In two steps, the measurement value and the motion value, one needs to do convolution and one needs to do multiplication.
Measurements are obtained using multiplication, and motion values are obtained using convolution.
