ABSTRACT:
A no-hit switching apparatus includes a phase comparing circuit, a first selecting circuit, a second selecting circuit, a memory circuit, a read address counter, and a switching circuit. The phase comparing circuit compares the phases of two received signals. The first selecting circuit selects a signal with a smaller phase delay from the two received signals on the basis of the comparison result in the phase comparing circuit. The second selecting circuit selects a signal with a larger phase delay from the two received signals on the basis of the comparison in the phase comparing circuit. The memory circuit stores the signal selected by the first selecting circuit. The read address counter reads out the signal stored in the memory circuit with the phase of the signal with the larger phase delay. The switching circuit switches between the signal read out by the read address counter and the signal selected by the second selecting circuit.
