Signal Conditioning
Analog Input
© National Instruments Corporation
This chapter discusses signal conditioning and describes how to build
systems such as filters and attenuators for passive analog input signal
conditioning.
Each differential analog input has seven open positions for signal
conditioning components. Six of these positions are designated as resistors,
and one is designated as a capacitor. The board is shipped with jumpers in
two positions for each input. The equivalent circuit of one input is shown
in Figure 4-1. You can use the board when the MIO board is configured for
both 16 single-ended inputs and eight differential inputs. For thermocouple
and other low-level applications, you can obtain best results when using
differential inputs. For specific applications illustrating signal conditioning
with both single-ended and differential inputs, refer to
later in this chapter.
