Abstract
Novel but very simple expressions characterising second-order discrete-time filters are presented. The parameters used are the centre angular frequency and the 3 dB bandwidth. The sensitivity analysis points out that Q (=¿0/¿b) has been misused as the measure related to sensitivity performance of discrete-time filters. Actually the sensitivity is approximately proportional to 1/¿0¿b for narrowband filters.
