The output from "add" block is a real plus imaginary signal,but the Power Amplifier requires complex input and output a complex signal as well.The Bandpass filter requires a real input.Anyone knows the way to change from "double to double(c)" meaning from real to complex signal, and vice versa?Thanks for your help!!
I cant see your picture, but converting between double to double complex and vs. is easy.
use real-imag to complex from simulink toolbox from Math Operations part
Hi,thanks for your response.Erm..I know about the Real-Imaginary to complex and complex to Real-Imaginary block.But how if there is only one input(double) and I need to change it to double(complex) so that It matches with another block which requires a complex input?
I wonder how come after the Real + Imaginary at "add block",the output from "add block" is not complex value?
Hope you all can help me on this.Thanks a lot!!!
