Use TA7796 to form an equalizer

Figure 1-99 is a five-segment equalization circuit composed of a dedicated integrated equalization circuit TA7796. In the circuit, the common
voltage amplifier and transistors for analog inductors are integrated into one circuit. Among them, the operational amplifier Ai is a common voltage amplifier , and VTi-VTs is a transistor used as an analog inductor . It, the built-in resistor and the external capacitor component form five analog inductors. These five analog inductors form five series connections with the capacitors ‰~CA5 respectively. The resonant circuit has center frequencies of 100Hz, 330Fk, 1"7, 3,3Ⅺ7 and 10kHz respectively.
