For example, in ultrasound applications, the DC offset from VGA (variable Gain amplifier) varies at different gains. Such a variable offset can introduce artifacts in ultrasound images especially in Doppler modes. Analog filter between ADC and VGA can be used with added noise and power. Digital filter achieves the same performance as analog filters and has more flexibility in fine tuning multiple characteristics. ADS5294 includes optional 1st order digital high-pass IIR filter. Its block diagram is shown in Figure 60 as well as its transfer function (6) Figure 60. HP Filter Block Diagram Figure 61 shows its characteristics at k=2 to 10. Figure 61.
