How to convert a varying (Hall) pulse signal to frequency in simulink?

This question is about modeling an control system of an internal combustion engine.

One of the input signals of the simulink model will be a Hall signal from a crankshaft posistion sensor. This signal will vary over time, as this engine will operate between the idle and maximum revolutions per minute. The signal will be used to time the engines injection and ignition system.

I have read multiple questions regarding the same topic but in those cases, the frequency was fixed. Since I have a varying signal, I was wondering if this is even possible to build in simulink? If possible, is there a block for which I am missing?

hello

see attachement

make sure the sampling frequency is set according to your preference (here it's 100 kHz)

all the best
