A discrete time (DT) lowpass filter having various advantages is described. In an exemplary design, the DT lowpass filter includes a decimating DT filter (which may include a passive DT FIR filter and/or a passive DT IIR filter) and an active DT filter. The decimating DT filter receives ...
TheLow-Pass Filter (Discrete or Continuous)block implements a low-pass filter in conformance with IEEE 421.5-2016[1]. In the standard, the filter is referred to as a Simple Time Constant. You can switch between continuous and discrete implementations of the integrator using theSample timeparamete...

In disturbance observers [1-5], the design of low pass filter(socalled Q-filter) has been a central issue. However, the effect of the Q-filter on the performance and robust stability has not been clarified yet, specifically in discrete-time domain. In this paper, we investigate this probl...
Finally, we explain why an integrator acts a lowpass filter from both time and frequency domain perspectives. Why is integrator a lowpass filter? An integrator maintains a running sum of past samples. In time domain, the summation of a large number of values tends towards a mean value. When...
在Simulink中,设置Discrete Filter(离散滤波器)参数主要涉及以下几个方面: 滤波器类型:首先需要确定滤波器的类型,例如低通(Low-pass)、高通(High-pass)、带通(Band-pass)或带阻(Band-stop)等。 滤波器系数:离散滤波器的主要参数是滤波器系数,包括分子(Numerator)和分母(Denominator)系数。这些系数决定了滤波器的频率...
