SCXI low-pass filter input module

The 8-channel elliptical low-pass filter input module for SCXI - SCXI‑1141 is a programmable filter module that is ideal for anti-aliasing applications. Although all channels must be set to the same cutoff frequency, you can program the signal of a low-pass filter for one channel to be bypassed individually. The combination of analog filter and switched capacitor filter not only provides 10,000 discrete software-programmable cut-off frequencies for users to choose from flexibly, but also maintains the low noise performance of traditional continuous time active filters. The module also provides an external clock input and output to set the filter cutoff frequency using an external clock in tracking filter applications.

The SCXI-1141 programmable filter module plays an important role in a variety of applications, such as communication, signal processing, audio processing, etc. By programmatically adjusting the characteristics of the filter, users can better adapt to different working environments and signal types for more efficient signal processing or a better audio experience.

Specific to the implementation mode, the SCXI-1141 programmable filter module may adopt digital or analog circuit technology. A digital filter module is usually based on a digital signal processor (DSP) or microcontroller and is programmed to control its filtering algorithm. The analog filter module may contain elements such as adjustable resistors and capacitors, and the filtering characteristics can be adjusted by changing the values of these elements.
