Implementing fractional delay filters in FPGA needs a cost-effective approach. This paper tries to clarify a misconception in fractional delay filter design, especially the phase delay and group delay behavior of low pass and high pass filters. Starting with the ideal filter frequency response, followed by practical filter simulation, two important delay factors are compared side by side. Mathe...

A plenty of research about thresholding methods in wavelet domain has been proposed by many authors. Multiwavelet domain can be decomposed as scalar wavelets and differently according to the structure of scaling functions. When scaling functions are symmetric-antisymmetric, the antisymmetric part is low pass filter in mathematical formula. But in practice it works as high pass filter because of...

This study compared the filtering effects on the auditory evoked potential of zero and standard phase shift digital filters (the former was a mathematical approximation of a standard Butterworth filter). Conventional filters were found to decrease the height of the evoked response in the majority of waveforms compared to zero phase shift filters. A 36-dB/octave zero phase shift high pass filter...

This paper presents a single current controlled current conveyor trans-conductance amplifier (CCCCTA)based multi-input single output (MISO) voltage-mode universal biquad filter. The proposed filter employs only single CCCCTA, two capacitors and one permanently grounded resistor. The proposed filter realizes all the standard filter functions i.e. low pass (LP), band pass (BP) and high pass (HP),...

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...

The paper presents a new voltage-mode universal filter using a differential voltage current conveyor transconductance amplifier (DVCCTA). It has three inputs and single output. The proposed circuit can simultaneously realize low-pass, band-pass, and high pass, band reject and all pass filter functions without changing the circuit topology and passive elements. The circuit exhibits a good freque...

A planar band pass filter topology is built using broadside coupled structure. The design is aimed at achieving pass band that covers the frequency range from 3.1GHz to 10.6 GHz. as required by modern Ultra Wide Band (UWB) indoor and outdoor communication systems . Multiple unlicensed users could share spectrum previously allocated to the users, including licensed users, on a non-interference b...

Two new current mode fully differential current conveyor (FDCCII) based multifunction filter configurations are proposed. The first proposed current mode universal filter with single input and two outputs, which can simultaneously realize current-mode low-pass (LP) and band-pass (BP), filter responses employing single FDCCII. The second proposed current mode universal filter with one input and ...
