Which of the following measures a filter’s ability to reject signals in adjacent channels?
Passband ripple
Phase response
Shape factor✓Ճիշտ պատասխան
Noise factor
Բացատրություն
Shape factor compares the filter's bandwidth far down its skirts with its bandwidth at the reference point. The closer that ratio is to one, the steeper the skirts and the better the filter keeps adjacent-channel signals out.
