Abstract
A transmission apparatus, a signal sending apparatus, and a signal receiving apparatus, and a transmission method, a signal sending method, and a signal receiving method capable of solving a problem of metastability and suppressing a delay of a signal when sending and receiving apparatuses having different operation clock frequencies send/receive the signal representative of control information, for example. Included are a sending part that operates in synchronization with a first clock having a first period to output a transmission signal having a signal level that is inverted in response to an input of a first pulse signal corresponding to the first period and a receiving part that operates in synchronization with a second clock having a second period to output a second pulse signal corresponding to the second period in response to inversion of a signal level of the transmission signal.
