Abstract
A signal processing device and signal processing method. A plurality of tuner circuits includes at least one that selectively provides a signal from among a plurality of signal bands potentially in an input signal in response to a control signal having a transition between a first state and a second state. A correction circuit corresponds to at least one of the plurality of tuner circuits, and is configured to receive the control signal and provide a corrected control signal for the tuner circuit. The corrected control signal has a gradual transition between the first state and the second state as compared to the transition between the first state and the second state in the control signal.
Claims29
A signal processing device, comprising:
- a splitter circuit configured to receive an input signal and distribute the input signal to a plurality of tuner circuits, the plurality of tuner circuits respectively being configured to selectively provide a signal from among a plurality of signal bands in the input signal in response to a control signal having a transition between a first state and a second state;
- and
- a correction circuit, corresponding to at least one of the plurality of tuner circuits and disposed between the splitter circuit and a respective tuner circuit, configured to receive the control signal and provide a corrected control signal for the respective tuner circuit, the corrected control signal having a gradual transition between the first state and the second state as compared to the transition between the first state and the second state in the control signal.
A signal processing device, comprising:
- splitter means for distributing an input signal;
- means for selectively providing a signal from among a plurality of signal bands in the input signal in response to a control signal having a transition between a first state and a second state, and for receiving a corrected control signal corresponding to the control signal;
- and
- means for correcting the control signal, which is disposed between the splitter means and the means for selectively providing a signal and which receives the control signal and provides the corrected control signal for the means for selectively providing the signal, the corrected control signal having a gradual transition between the first state and the second state as compared to the transition between the first state and the second state in the control signal.
A signal processing method, comprising:
- receiving an input signal and distributing the input signal to a plurality of tuner circuits;
- selectively providing, by at least one of the plurality of tuner circuits, a signal from among a plurality of signal bands in the input signal in response to a control signal having a transition between a first state and a second state;
- and
- receiving the control signal, by a correction circuit disposed between the input signal and a respective tuner circuit, and providing a corrected control signal for the respective tuner circuits, the corrected control signal having a gradual transition between the first state and the second state as compared to the transition between the first state and the second state in the control signal.
