hello, i have created 3 filters with fdatool, a low pass (20-250 hz), a band pass (250-2000 Hz) and a high pass (2000-20000 Hz9, export these 3 filters and put them in simulink to test the 3 filters The problem is that when introducing a 100 Hz signal it gives me a signal of 1 [V] in the low pass and 0.2 in the band pass and 1 [V] in the highpass. The expected response is that it delivers 1 [V] in the band pass and the other signals are attenuated ( Figure 1). Attached images of the configurations

Fs for band pass is 4400, and for high pass 44000

In the end I solved it as follows: Calculate twice the maximum signal treated (2 * 20000) and take that as the Fs for all filters. For the scope sample time I put (1/44000). The Fs must be greater than twice the maximum frequency treated (for Nyquist), adopt it as 44000.
