| Popis: | The article describes designing of a simple active filter circuit for an amplitude RC equalizer on three operational amplifiers with reconfigurability of all three main parameters: resonance frequency transfer coefficient and Q. Reconfigurability of these parameters is carried out by two variable resistors and one potentiometer. To adjust the resonance frequency, a dual potentiometer is not required. The quality factor and the transmission coefficient are adjusted within one decade. The tuning of the resonance frequency is possible within one octave without a significant effect on the Q-value. The obtained scheme of a simple tunable amplitude corrector is suitable for working in the range of low frequencies to video frequencies. |
