题目如下 ：using the bilinear transformaion method,design a digital Butterworth
highpass filter operating at a sampling rate of 1.5MHz with the following specifications:passband edge at 600kHz,stopband edge at 210kHz,peak passband ripple of 0.4dB,and minimum stopband attenuation of 45dB.(a)what are the specifications of the analog highpass filter?(b)what are the specifications of the analog prototype lowpass filter?(c)Show all pertinent transfer functions.
Plot the gain responses of the prototype analog lowpass filter,analog highpass filter,and desired digital highpass filter.
SHow all steps.
老师要求在matlab上实现，希望能给出详细步骤，最好给出注释，再次感谢~~!
