WebThis is a simple type of low pass filter as it tends to smooth out high-frequency variations in a signal. (We will look at more effective low pass filter designs later). 6. Three-term average filter: y = x + x n3 n n-1 +x n−2 This is similar to the previous example, with the average being taken of the current and two previous inputs: WebAs a general rule, a phase lag (i.e. a delay) is required for a low-pass filtering effect. So I would expect the time delay to increase as the filter bandwidth decreases. The complex...
