WebMar 30, 2024 · An ideal anti-alias filter passes all the appropriate input frequencies (below f1) and cuts off all the undesired frequencies (above f1). However, such a filter is not physically realizable. In practice, filters look as shown in illustration (b) below. They pass all frequencies < f1, and cut-off all frequencies > f2. sign in optonline webmail
