TU Braunschweig · Journal of China Institute of Communications · 1985
This paper gives the 7×7 and 15×15 masks of the 2D lowpass sequency aliasing digital filter, those masks are derived from infinite great matrix. The computer analogs c(?)lculated results are shown that they have less error as compared with normal 7×7 and 15×15 masks.
