摘要: In this paper, the stability of quantized digital filter utilizing saturation nonlinearity has been investigated through a Lyapunov approach. A new extended conditions will be proposed for by using with logarithmic quantizers, which have proofed giving numerical example and theoretical derivation. We got these bringing in quantization dependent functions.
