Noise cancellation using single band reject ideal filter

Hai. I'am new with Scilab. Can I know, how to write the coding for following question?

Perform noise cancellation using a SINGLE band-reject ideal-filter, and obtain the original message.

  1. Design the filter in frequency domain.
  2. Use an ideal filter, H where:
    • H=1, pass-band frequency
    • H=0, reject-band frequency
