Figure 23.
Active power filter
A more effective solution, named "Active Power Filter" by STMicroelectronics, is shown in
Figure 23. The proposed circuit can be realized by combined power amplifiers and
12-dB/octave or 18-dB/octave high-pass or low-pass filters.
The component values calculated for fc = 900Hz using a Bessel 3rd order Sallen and Key
structure are:
C1 = C2 = C3 = 22 nF
R1 = 8.2 k
R2 = 5.6 k
R3 = 33 k
In the block diagram of Figure 24 is represented an active loudspeaker system completely
realized using power integrated circuit, rather than the traditional discrete transistors on
hybrids, very high quality is obtained by driving the audio spectrum into three bands using
active crossovers (TDA2320A) and a separate amplifier and loudspeakers for each band. A
modern subwoofer/midrange/tweeter solution is used.
