Hi, i want to plot the transfer funtion of this cic filter with matlab. I got no idea how to do it...pls help..thanks



This is the result i should get
 

the plot u wanted is between the transfer function and the frequency range from 0 to 1.5MHz. Make a frequency vector from 0 to 1.5MHz with 100Hz step. then u will have to numerically evaluate ur transfer function in matlab for the vector. Use the plot function to plot the graph like plot(freq_vector, transfer_function_evaluated).

hope that helps.
 

but how to evaluated the Z in the transfer funtion?
