For calculating the image rejection ratio in ADS, we give two signals as system input, "original signal" and the "image signal + 10Khz ".
In my receiver I am down converting my signal to 20Mhz. So for calculating IRR, What i have to do ?
Shall i take peek difference of "20Mhz" and "20Mhz...

According to the double quadrature model what will be the input to IF polyphase filter ?
Plz see the attached figure.........
need help .. its urgent !!!!!!!!:cry:
(in terms of Iin+, Qin+, In-, Qin- )?
image rejection ratio
For any system level design, at which point we have to calculate the image rejection ratio?
Is that at the final output i.e., after Amplifire or can calculate after any subsystem?
I want to subtract the output of the polyphase filter ....
please see the attacted file... named "polyphase filter.jpg"
Signals may be of different phase and different amplitude....
Please suggest me in each possibility i.e., ... in case of different phase, in case of different amplitudes and...
