MATLAB Realization to simulate analogue Low-pass filter
Lei Qian · Journal of Hunan University of Science and Engineering · 2009
This paper mainly describes the process of how can we carry out the numerical modeling filter from the ideal low-pass filter which can’t carry out by the physics. Here, Butterworth-respond method is adopted to approach ideal characteristic, and the rank order of the filter showed to be the main factor that influences a low-pass filter accuracy. In the end, we link an example with MATLAB to realize the program design of analogue low-pass filter
