In this paper, we propose a method for designing a low-delay integer-order differentiators based on maximally flat in the passband and equiripple criteria in the stopband. The proposed function consists of two functions. One of the functions has low-delay and flat characteristics in both the passband and the stopband. The other function is designed so that the whole function has an equiripple characteristic in the stopband. The low-delay low-pass/band-pass integer-order differentiators designed by the proposed method realize highly accurate differential estimation near the desired frequency and sharp cutoff characteristics.
