ABSTRACT:
A memory circuit write-in system comprises a first circuit for supplying a digital signal including a time base fluctuation component, where one frame of the digital signal is constituted by at least a synchronizing signal and information data and the digital signal has a first repetition frequency with a period of one frame of the digital signal, a memory circuit for writing therein and reading out therefrom the digital signal supplied from the first circuit, and a second circuit for applying a write-in control signal to the memory circuit. The write-in control signal includes no time base fluctuation component and has a second repetition frequency substantially equal to the first repetition frequency, and the memory circuit is controlled by the write-in control signal so that write-in of the digital signal is carried out with a write-in period in a range of two times within the one frame period.
