i want to see the response of the signal in the frequency domain rather than time domain but i don't want to use specturm analyzer and i think there is block in simulink present the signal in frequency domain but i can't find it

Hello @ANAS HAMZAH,

As per my understanding, you are trying to convert the signal from time domain to frequency domain. That is, you want the information about the magnetude and phase of perticular frequency component present in the signal. This can be achieved by FFT (Fast Fourier Transform). There is "FFT" block in Simulink. Refer to the documentation for more information regarding the block.

You can also refer to the below given example that illustrates its usage:

I hope this answers your question !!
