摘要：

Theoretical description and frequency response characteristics of selected real-time digital filters is presented, including infinite impulse response (IIR) and finite impulse response (FIR) filters. The application of different filtering procedures to computer-simulated noisy signals, corresponding in shape to a common asymmetric flow-injection response, suggests that the use of IIR filters is the most effective for the removal of high-frequency noise.
