Abstract
The present technology relates to a signal processing apparatus and method capable of increasing a harmonic rejection ratio while suppressing an increase in power consumption. In one aspect of the present technology, two local signals having a 1/3 duty ratio and phases mutually shifted by a 1/2 period are mixed with each signal of a differential signal, and a difference between results of the mixing of the two local signals is calculated. The present technology can be applied to, for example, a signal processing apparatus, a transmission apparatus, a reception apparatus, a communication apparatus, an electronic apparatus having a transmission function, a reception function, or a communication function, or a computer that controls those apparatuses.
Claims20
A signal processing apparatus, comprising
- a mixing section that has a differential configuration, mixes two local signals with each signal of a differential signal, and calculates a difference between results of the mixing of the two local signals, the two local signals having a 1/3 duty ratio and phases mutually shifted by a 1/2 period.
A signal processing method, comprising
- mixing two local signals with each signal of a differential signal and calculating a difference between results of the mixing of the two local signals, the two local signals having a 1/3 duty ratio and phases mutually shifted by a 1/2 period.
A signal processing apparatus, comprising
- a generation section that generates two local signals to be mixed with a differential signal, the two local signals having a 1/3 duty ratio and phases mutually shifted by a 1/2 period.
A signal processing method, comprising
