FilterLab Filter Design Software Part Number: filterlabdesignsoftware Summary: FilterLab® is an innovative software tool that simplifies active filter design. Although elliptic filters offer high Q and a sharp transition band, they lack a constant group delay in the passband, which implies more ringing in the time-domain step response. 0 A low pass filter calculator is the calculation of cut-off frequency, voltage gain, and the phase shift of the LPF circuit. We know that for different frequencies in the input the circuit behaves either as an open or short circuit. Example 2 : Elliptic low pass filter circuit. Filters are linear circuits that can be represented as a transfer function of the form shown in Equation 1, which corresponds to the simple block diagram in Figure 1. In order to minimize the delay ripple in the pass-band of the LTC1560-1, an allpass filter (delay equalizer) is cascaded with the LTC1560-1, as shown in Figure 38.160.
