Kami mencadangkan dua kaedah untuk mengelakkan herotan papan dam yang disebabkan oleh ralat panjang perkataan terhingga. Kaedah pertama memperoleh panjang bit pekali penapis yang diperlukan untuk mengelakkan herotan papan dam di bawah panjang perkataan tertentu. Dalam kaedah kedua, herotan papan dam boleh dielakkan dengan menggunakan struktur lata yang terdiri daripada isirong pegangan sifar dan penapis invarian masa yang difaktorkan daripada penapis dengan struktur untuk mengelakkan herotan papan dam di bawah sistem linear. Ia ditunjukkan melalui simulasi bahawa kita boleh mengelakkan herotan papan dam dengan menggunakan kaedah yang dicadangkan ini.

Abstract: We propose two methods for avoiding the checkerboard distortion which is caused by finite word length error. The first method derives the bit length of filter coefficients required for avoiding the checkerboard distortion under a certain word length. In the second method, the checkerboard distortion can be avoided by using the cascade structure which consists of zero-hold kernel and a time-invariant filter factorized from a filter with structure for avoiding the checkerboard distortion under linear systems. It is demonstrated by simulations that we can avoid the checkerboard distortion by using these proposed methods.
