Pulse Code Modulation (PCM) encoder handbook for Aydin Vector MMP-600 series system
S. F. Currier, W. R. Powell · NASA Technical Reports Server (NASA) · 1986
The hardware and software characteristics of a time division multiplex system are described. The system is used to sample analog and digital data. The data is merged with synchronization information to produce a serial pulse coded modulation (PCM) bit stream. Information presented herein is required by users to design compatible interfaces and assure effective utilization of this encoder system. GSFC/Wallops Flight Facility has flown approximately 50 of these systems through 1984 on sounding rockets with no inflight failures. Aydin Vector manufactures all of the components for these systems.
