Abstract
PURPOSE: To receive an input wave form data in a relatively short time by adding a gate circuit and a N/P-adic counter to the device and by reducing a waiting time.
CONSTITUTION: The voltage control oscillator 13 synchronizes with the input in phase, and oscillates pulses at frequency of N times the input. The (N+1)-adic counter 20 counts output pulses of the oscillator 13 continuously and provides an output pulse every (N+1) count. The data receiving unit 1 operates on synchronizing itself with the output pulse, and consequently a sample value of the input is obtained. At the same time, the flip-flop 26 of the gate 27 is set, the gate 27 is opened by the output of the flip-flop 26, and the N/P-adic counter 28 starts to count the output pulse of the oscillator 13. When the counter 28 counts the pulse by N/P, an output pulse is emitted, a sample value of the input is obtained by synchronizing itself with the output pulse. After this, the same operation is repeated. The flip-flop 26 is reset by the output of the counter 29 and the gate 27 is closed.
