In this paper, an optimal design of linear phase digital high pass finite impulse response (FIR) filter using Particle Swarm Optimization with Constriction Factor and Inertia Weight Approach (PSO-CFIWA) has been presented. In the design process, the filter length, pass band and stop band frequencies, feasible pass band and stop band ripple sizes are specified. FIR filter design is a multi-modal...

A band-pass filter with 70% bandwidth, effectively functioning as a pseudo-high pass filter has been designed and implemented using suspended strip-line technology. In principle such a filter can easily be fabricated by cascading low pass and high pass filters, but it is difficult to fabricate high pass filters in suspended stripline, and this filter is expected to overcome this difficulty. The...

The paper introduces a novel structure of dual-band filtering Wilkinson power divider (WPD). Its essential component is bandpass filter (BPF), implemented using coupling lines and two T-shaped resonators. BPF incorporated into the to suppress unwanted harmonics within circuit. latter achieved owing wide stopband filter. designed WPD can third in both channels with high levels attenuation. opera...

In the present paper a multilayered microstrip low pass filter using complementary split ring resonator is proposed. A design for prominent stop band characteristics with minimized ripples is presented, while maintaining the filter pass-band performance. By properly designing and integrating the complementary split ring resonators with the low pass filter, the proposed structure exhibit superio...

A universal biquadratic filter using single universal voltage conveyor (UVC), two resistors and two capacitors is presented in this paper. The proposed structure has three inputs and one output and can realize all the five standard biquadratic filters: low-pass (LP), high-pass (HP), band-pass (BP), band-reject (BR) and all-pass (AP) from the same circuit configuration. The presented universal f...

This paper presents an optimal design of linear phase digital high pass finite impulse response (FIR) filter using Improved Particle Swarm Optimization (IPSO). In the design process, the filter length, pass band and stop band frequencies, feasible pass band and stop band ripple sizes are specified. FIR filter design is a multi-modal optimization problem. An iterative method is introduced to fin...
