<p>PURPOSE:To obtain the periodical pulse in the exchanging system with comparatively simple configuratin, by reading out the content of memory. CONSTITUTION:''0'' and ''1'' are written in as shown in Fig. 3, in the memory (1). The 0 bit is the used to obtain the initialize condition, and the 1 bit to (n-1) bit are stored corresponding to the periodical pulse train of a given conditions. The basic pulse of a given period shorter than the pulse train repetitive period requested is inputted from 7, and the monotation address counter 2 performing address designation is advance. Every pulse is read out toward word and it is tentatively stored in the register 3, and the pulse trains of (n-2) types can be obtained from the terminal 5. For example, the output pulse of the second bit it ''L'' for first 2.5 sec. and ''HLH'' for every 0.5 second afterward and again returned to ''L''.</p> |
