A signal processing apparatus subtracts a second sampled signal from a first sampled signal to generate a first resultant signal, the first sampled signal being delayed for a time period of 4nT to create the second sampled signal, wherein n is a positive integer and T is a sampling time period. The apparatus adds the first resultant signal to a third sampled signal to generate a second resultant signal, the second resultant signal being delayed for a time period of 4T to create the third sampled signal. The apparatus subtracts a fourth sampled signal from the second resultant signal and outputs a third resultant signal, the second resultant signal being delayed for a time period of 2T to create the fourth sampled signal. A signal processing method corresponding to the signal processing apparatus is also provided.
