      Phase Response For a first-order low-pass filter, v OUT always lags v IN by some phase angle betweeen 0 and 90 . The vector diagrams to the right show why. The RL vector diagram at the top properly shows that v L leads v R by 90 . However, the input volta

      A low-pass filter, also known as anti-aliasing or “blur” filter, was designed by camera manufacturers to eliminate the problem of moiré by blurring what actually reaches the sensor. While extreme details are lost in the process, the problem of moiré is co
