This paper presents a new versatile high input impedance voltage-mode universal filter with multiple-input multiple-output (MIMO) based on single-ended operational transconductance amplifiers (OTAs) and grounded capacitors. The proposed circuit can work as a two-input four-output filter and a three-input single-output filter without changing the circuit topology. The natural frequency (ωo) and the...
This paper presents a design of digital filter for digital hearing aids application. The structure of filter is consist a combination in parallel form of IIR (Infinite Impulse Response) a low-pass, a band-pass and a high-pass filter. This study shows an advantage of IIR filter can gives a good result in the low complexity digital hearing aids which leads to low hardware resources requirement and low...
