Hi,

I am going to design a circuit and it's important for me to know the relation between the phase of the transmitted signal, and the received one.
I know what the phase of the original transmitted signal is, but after using mixer and down converting the received signal to an IF frequency, I think the phase of the signal would be changed due to the filter used in the mixer. I wonder if what I think is correct, and if so, is there any way to solve this problem?
