The FIR FFT core is intended for the signal filtering. With the FIR filter of large impulse response length which exceeds up to Ni = 512 samples. Each FFT iteration dates are computed by the computational unit, called FFTDPATH, another words, data path for FFT calculations. FFTDPATH calculates the radix-2 FFT butterfly in the high pipelined mode. Therefore in each clock cycle one complex number...

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 ...

In this paper, two new electronically tunable filter configurations are proposed. The proposed filters operate current-mode (CM), voltage-mode (VM), transimpedance-mode (TIM) and transadmittance-mode (TAM). The first configuration realizes second-order VM band-pass and TAM high-pass filter characteristics from the same configuration. The second one realizes second-order TIM band-pass and CM low...

A new configuration for realizing currentmode multifunction filter using current feedback amplifiers for a single current input source is presented. The proposed current-mode circuit realizes simultaneously low pass, high pass and band pass filters where as notch and all-pass filter functions can also be realized by addition and/or subtraction of various filter functions without any substantial...
