Abstract

IF receivers are known which receive an antenna signal and normally supply an IF signal. A problem can arise resulting in a phase and or frequency error as result from for example adjacent channel. To solve this problem a correction device is proposed that corrects the phase and/or frequency error in the I and/or Q signals.
