log_psd
This function takes the n time domain samples (real or complex)
and finds the psd by taking (fft/n)^2. The two sided spectrum is
produced by shifting the psd The array freq provides the appropriate
frequency values for plotting purposes.
By taking 10*log10(psd/max(psd)) the psd is normalized values beow 60db
are set equal to -60db

设计数字滤波器
n1.用双线性变换法设计IIR DF的原理及具体设计方法,熟悉用双线性变换法设计IIR DF的计算机编程。
n2.用双线性变换法设计的DF的频响特性,了解双线性变换法的特点。
n3.用双线性变换法设计BW和CB型DF的全过程。
设计IIR数字滤波器的一般步骤:
Ø把给出的数字滤波器的性能指标转换为模拟滤波器的性能指标
Ø根据转换后的性能指标,通过滤波器阶数选择函数,来确定滤波器的最小阶数N和固有频率Wn
Ø由最小阶数N得到低通滤波器原型
Ø由固有频率Wn把模拟低通滤波器原型转换为低通、高通、带通、带阻滤波器
Ø运用脉冲响应不变法或双线性变换法把
