I am using MATLAB R2025b and trying to design FIR filters using window function in Simulink using the Digital Filter Design Block, when I run the model it gives an error message box saying: "fliiter design is not valid. please redesign". I tried generating MATLAB code of the block and the code runs with no errors.

parameters I used:

low pass filter
rectangular window
order = 50
Fs = 48000 Hz
Fc = 10800 HzI am using MATLAB R2025b and trying to design FIR filters using window function in Simulink using the Digital Filter Design Block, when I run the model it gives an error message box saying: "fliiter design is not valid. please redesign".
