It is convenient to normalize W(ω) to unity in the stop band and set W(ω)=δ2/ δ1 in the pass band.
Which of the following defines the weighted approximation error?
The error function E(ω) does not alternate in sign between two successive extremal frequencies.
At most how many extremal frequencies can be there in the error function of ideal low pass filter?
The filter designs that contain more than L+2 alternations are called as:
If M is the length of the filter, then at how many number of points, the error function is computed?
