ABSTRACT:
A signal apparatus is provided. The signal value holding apparatus including a determining section to determine a magnitude relationship between a signal value of an input signal and a signal value of a prescribed feedback signal, a first holding section to hold the signal value determined to be larger by the determining section, a subtracting section to subtract a prescribed value from the signal value held by the first holding section and output a result as the feedback signal, and a second holding section to receive the signal value held by the first holding section and hold the signal value supplied from the first holding section when the signal value of the input signal becomes smaller than the signal value of the feedback signal based on a determination result of the magnitude relationship between the signal values by the determining section.
