2.0 Modes of Operation (Continued)

MODE 4: Allpass, Bandpass, Lowpass Outputs

(See

Figure 13

)

Due to the sampled data nature of the filter, a slight mismatch of f

and f

occurs causing a 0.4 dB peaking around f

of the allpass filter amplitude

response (which theoretically should be a straight line). If this is

unacceptable, Mode 5 is recommended.

MODE 5: Numerator Complex Zeros, BP, LP

(See

Figure 14

)
