I am trying to find the counts per minute of a geiger counter signal using Simulink.
I managed to get the signal in a digital/binary form shown below:
I want to figure out how many pulses there are in a given timefram (1-3 seconds)

Let A be your Interval test signal in timeseries format. Then
Pulses_1_3secs = nnz(out.A.Data((out.A.Time >= 1) & (out.A.Time <= 3))

By the way, I am using Simulink, so the method that you proposed may not work.

The block under sum block in the second pic is *Unit Delay* block.
The first PWM block *Run at fixed interval* is ticked as model runs at fixed sample time.
