As Figure 4-4 shows, the SCXI-1141/1142/1143 module provides 80 dB attenuation above 1.5 times the cutoff frequency for the SCXI-1141 module, six times for the SCXI-1142 module, and 3.2 times for the SCXI-1143 module. The SCXI-1141, which incorporates an elliptic filter, is designed to provide maximum attenuation immediately above the cutoff frequency. Therefore, it is the ideal choice for applications in which you must remove signals very near the cutoff frequency. Figure 4-4. Typical Magnitude Response of the SCXI-1141/1142/1143 Module Filters Figure 4-5 compares the magnitude response of the SCXI-1141/1142/1143 modules within the passband. The passband magnitude response begins to drop off immediately for the SCXI-1142 module. The SCXI-1141 performs much better than the SCXI-1142 in the passband, but it still exhibits about 0.1 dB of ripple in magnitude in the passband. The SCXI-1143 module Butterworth filter is designed for maximum flatness in the passband and is nearly perfectly flat in most of the passband. For this reason the SCXI-1143 module filter is the ideal choice for applications where flatness in the passband is critical. 1 x 10–3 Bessel (1142) –80 dB Intersection Elliptic (1141) 0.01 0.1 1 10 –200 –150 –100 –50 0 50 Frequency (Normalized) Gain (dB) Butterworth (1143) –80 Chapter 4 Theory of Operation SCXI-1141/1142/1143 User Manual 4-8 Figure 4-5. Typical Passband Responses of the SCXI-1141/1142/1143 Module Phase Response Figures 4-6 through 4-8 illustrate the phase response characteristics of the SCXI-1141/1142/1143 module filters. Figure 4-6 shows the phase shift as a function of frequency (normalized so that the cutoff frequency = 1). In an ideal filter, this would be a linear relationship. Figure 4-7 shows the deviation of the actual phase response from an ideal (linear) response. Generally, phase response is described in terms of the differential nonlinearity, or group delay. Group delay is defined as the negative derivative of the phase shift with respect to the frequency. In the ideal filter, group delay is a constant
