设计一个在0.45π处具有3dB截止角频率的一阶无限冲激响应低通滤波器和一阶无限冲激响应高通滤波器。用matlab计算并画出它们的增益响应，并用matlab证明两个滤波器是全通互补和功率互补的。涉及画图的频率范围[- π, π]，间隔设置π /100。-Design a 3dB cutoff at 0.45π with angular frequency at the first order infinite impulse response low-pass filter and the first order IIR high-pass filter. Using matlab to calculate and draw them gain response, and with matlab that two all-pass filters are complementary and power complementary. Involves drawing the frequency range [- π, π], interval π/100.
