I will be very glad to know if this kind of*. m code can be transferred to simulink block where the block accepts AC+DC as input and the out put as DC signal only. This example is quite good to know.

You can find an FFT block in the Power Spectrum Estimation library. There is also a Spectrum Scope in the Signal Processing sinks. If you don't have the Signal Processing Blockset, output your signal data to the MATLAB work space and compute and FFT from there. I hope that helps. @Saurabh - The blocks I think you are looking for are part of the Signal Processing Blockset. You can find an FFT block in the Power Spectrum Estimation library.

Can you tell me which block should i use to find fft and which scope block to see it? Thankyou. Sir,
