Abstract (en)
[origin: US4455540A] A band-pass filter comprising n principal linear resonators open at both their extremities, has integrated therewith a band suppressor function by means of p auxiliary linear resonators (p being an integer comprised between 0 and n+1), tuned to a frequency which is to be rejected and respectively connected to p resonators of the n principal resonators at a point situated close to the middle of the principal resonator in question.
