A novel comb compensator with a good passband deviation-complexity tradeoff
This paper presents a novel simple multiplierless comb compensator which exhibits a good tradeoff between the resulting passband droop compensation and introduced complexity. The filter is composed of two second order sections, both working at the lowest rate, and with sine squared magnitude characteristics. The first section remains the same for all comb parameters. The second section depends only on the number of the cascaded comb filters. A simple formula which relates compensator parameter and the number of cascaded combs, is derived. The comparisons with some known compensators are also provided in order to demonstrate the benefit of the proposed compensator.
Multiplierless Wideband and Narrowband CIC Compensator for SDR Application
This paper presents multiplierless CIC compensator for software-defined radio (SDR) application. The compensator is composed of two simple filters with sinewave form of magnitude responses. The parameters of the design are the sinewave amplitudes expressed as powers-of-two and estimated in a way to fulfill the absolute value of the maximum passband deviation of 0.25 dB and 0.05 dB, for the wideband and narrowband compensations, respectively. The proposed compensator requires maximum nine adders. The comparisons with the methods proposed in literature show the benefits of the proposed compensator.
PASSIVE AND LOW-ENERGY RESEARCH AND PRACTICES-DEHUMIDIFICATION
Methods of achieving acceptable indoor conditions in overheated, temperate, and underheated humid climates are discussed and compared. Desiccants and desiccant systems utilizing solid and liquid sorbents and various low-energy mechanical systems are described and evaluated.
