摘要： According to an embodiment, a signal conversion apparatus includes a control information generator and a selector. The control information generator generates first control information based on rate information indicating transmission rates of original signals. The first control information designates a first timing at which each of the original signals is sampled. The selector selects each of the sampled signals at a timing based on the first timing. The original signal group includes a first original signal at a first transmission rate and a second original signal at a second transmission rate. The first transmission rate is higher than the second transmission rate. The frequency of allocating the first timing to the first original signal is higher than a frequency of allocating the first timing to the second original signal.
