Final answer:
Given an initial angular frequency rotation speed estimate, the cutoff frequency for a low-pass filter should be set just above that speed. With a 2Hz rotation estimate starting around 3Hz for the cutoff frequency might be suitable.
Step-by-step explanation:
Regarding the initial cutoff frequency for a low-pass filter, if we are given an initial estimate of the angular frequency of rotation, we would typically want to set the cutoff frequency just above this rotation speed to ensure that the signal is not attenuated. Assuming the typographical errors are referencing a '2Hz' rotation speed (as 'tiz' likely stands for 'Hz' and 'spetd' for 'speed'), an appropriate initial cutoff frequency might be slightly above 2Hz to allow the signal to pass through while attenuating higher frequency signals. Therefore, without additional context, a good starting point for the low-pass filter's cutoff frequency could be:
- 2.0Hz as the baseline frequency of the rotation speed.
- Around 3Hz to slightly exceed the given rotation speed.
