Considering x[n]=1+sin((3*pi*n)/8 + pi/4) + cos ((9*pi*n/24) + pi/4) , please design a filter that will pass the sine-wave portion, but ignore everything else. What is the filter's input response h(t)? In a real filter, what would you have to do differently?

Multiply x[n] by cos((3*pi*n/8)+pi/4) and then add a DC component 1/2. This means shifting the x(w) to high centre frequencies and adding an ...
This solution is the design of a filter that passes the sine-wave portion, using the equation provided as a base, noting the filter's input response and its implications.
