Question

What is frequency warping effect? Explain how this effect is eliminated

Answer 1

Answer:

warping effect.Effect compresses the magnitude and phase response. This effect is called warping effect. Pre-warp our desired digital frequency and substitute that into the transformed digital filter function.

Explanation:

Answer 2

frequency warping effect is a capacity H(f) is performed by applying the unitary distorting administrator U to the capacity. (The administrator is characterized underneath, allude to the figure).  A few creators have utilized the idea hub distorting in association with the U administrator, be that as it may, the pivot (f) is unaltered on the grounds that the administrator is a H-> ~H mapping. Rather than twisting the pivot the administrator has made another, unitarily distorted portrayal ~H for the capacity H on the equivalent, unaltered hub. This activity could likewise be called recurrence mapping.  

How this effect is eliminated?

Recurrence twisting change is where one ghostly portrayal on a specific recurrence scale (e.g., Hz, f-space) and with a specific recurrence goals (frequently uniform) is changed to another portrayal on another recurrence scale (e.g., Bark or ERB-rate scale, v-area). The new portrayal has a uniform recurrence goals on the new scale - be that as it may, it has a nonuniform goals when seen from the old scale. The new recurrence scale (v-area) and the bygone one (f-space) are connected by a smooth and monotonic twisting (mapping) work v(f) with a positive subsidiary (dv/df > 0).
