Abstract

See full text

A signal filter includes a notch filter and a wideband filter. The notch filter is configured to perform a band-rejection filtering operation according to a band-rejection filtering property. The wideband filter is coupled to the notch filter, and is configured to perform a wideband filtering operation according to a wideband filtering property. The band-rejection filtering property includes a first cutoff frequency, a frequency bandwidth, a relatively high quality factor and a relatively low coupling coefficient. The wideband filtering property includes a second cutoff frequency, a relatively low quality factor and a relatively high coupling coefficient. The first and the second cutoff frequencies have a frequency difference therebetween. A ratio of the frequency difference to the frequency bandwidth is within a preset ratio range being from 2.5% to 20%.
