Tunable lumped-element notch filter with constant bandwidth

2010 IEEE International Conference on Wireless Information Technology and Systems, 2010
A varactor-tuned first-order (two-resonator) lumped-element absorptive notch filter with tunable operating frequency and constant absolute bandwidth has been introduced, along with an approach to its design. To reduce signal voltage across individual varactors, it is suggested to add additional pairs of stacked varactors in parallel, rather than in ...

Capacity of a Bandwidth Constrained Constant Envelope Signal

2006 IEEE 24th Convention of Electrical & Electronics Engineers in Israel, 2006
The capacity of constant envelope signals with bandwidth constraints has been an open problem for many years. In this paper we find a lower bound on this capacity, for second-moment bandwidth constrained signals. The bound is found by utilizing classic results on optimum angle modulation.
