Abstract
A level control circuit that generates output signal for level control includes: a control information storage that stores control information corresponding to a signal level, a control information circuit that outputs the output signal for level control corresponding to the signal level of a first input signal based on the control information stored in the control information storage; and an information update circuit that updates the control information of the control information storage according to the signal level of a second input signal.
Claims20
A level control circuit that generates output signal for level control comprising:
- a control information storage that stores control information corresponding to a signal level,
- a control information circuit that outputs the output signal for level control corresponding to the signal level of a first input signal based on the control information stored in the control information storage;
- and
- an information update circuit that updates the control information of the control information storage according to the signal level of a second input signal.
A level control method for generating level control output comprising:
- storing control information corresponding to a signal level in a control information storage, receiving a first input signal, and outputting control information corresponding to the signal level of this signal;
- and
- updating the control information of the control information storage according to the signal level of a second input signal.
A level control system comprising:
- a level control device that obtains an output signal subjected to level control with control information from an input signal;
- and
- a level control circuit that outputs the control information;
- the level control circuit further including
- a control information storage unit that stores the control information corresponding to the signal level of the input signal and outputs the control information corresponding to the level of the input signal;
- and
- an information updating unit that updates the control information of the control information storage unit according to the level of the output signal.
