What?s a Digital Filter?
– … The highest frequency to be transmitted is ?c, which is allso called the cut off frequency. The highest frequency to be sent is ?c, that is additionally shouted the cutoff frequency. Frequencies above cutoff are stopped from bypassing across the filter and they contain the filter halt band. Figure 3.1 Ideal low-pass Filter Characteristics The flawless reply of a low-pass filter is shown above. Though, a physical route cannot comprehend this response. The actual reply will be in finished as shown below, Figure 3.2 Actual low-pass Filter Characteristics It can be perceived that a tiny error is allowable in the bypass group, as the transition from the bypass group to the halt group…
