说明：  一阶RC低通滤波，MATLAB仿真分别实现一阶RC低通和高通滤波器，输入信号为正弦信号或者方波信号。 注意截止频率为f = 1/(2*pi*R*C)(The first-order RC low-pass filter and the MATLAB simulation realize the first-order RC low-pass filter and the high-pass filter respectively. The input signal is sinusoidal signal or square wave signal. Note that the cutoff frequency is f = 1 / (2 * pi * r * c))

This book is dedicated to the memory of James Huddleston, the editor at Apress who initiated this book project and encouraged the authors with his insights, loyalty, enthusiasm, and humor. Jim passed away in February 2007, an enormous loss to his family, Apress, and the authors.
