4.9.3.2 EQ Filters
4.9.3.3 Analog Simulation Filters
TLV320AIC34EVM Software
EQ, or parametric, filters can be designed on this tab (see Figure 19 ). Enter a gain, bandwidth, and a
center frequency (Fc). Either bandpass (positive gain) or band-reject (negative gain) filters can be created
Figure 19. EQ Filters
Biquads are quite good at simulating analog filter designs. For each biquad section on this tab, enter the
desired analog filter type to simulate (Butterworth, Chebyshev, Inverse Chebyshev, Elliptic or Bessel).
Parameter entry boxes appropriate to the filter type will be shown (ripple, for example, with Chebyshev
filters, etc.). Enter the desired design parameters and the response will be shown. (See Figure 20 .)
