Hi there![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
I have attached the magnitude and phase response of a low pass filter. The phase response is linear thus delaying all signals by the same amount. However, it is observed that there is a certain transition (circled) upward in the response.
What causes this occurrence?? I realize it happens at the valley between the pass band ripple and the stop band ripple and would like to know why..
Thanks!![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
