level 0 5 v data and their sampling rate can be changed from 8 sps to 128 sps the ddp 12 accepts pcm data from the m e 10 stores it and then outputs it since the storage capabilities of the delay device 12 are limited by volume in a missile application the delay device selects and stores only a limited number of m e data channels the delayed data is repeated several times at a high bit rate increasing the probability of retrieving the data that is stored during rf blackout the output bit rate is constant with the total storage capacity 524 288 bits equal to the bit rate so that storage readout transmission time is always 1 second typical configurations of the delay device 12 are as follows ______________________________________data delay number of datachannels time repetitions per second______________________________________128 1 sec 164 2 sec 232 4 sec 416 8 sec 8______________________________________ the ddp 12 outputs its complete contents every second i e there is an inherent 1 second delay in passing data through the delay device for longer delays fener channels are input so that for the configuration where 32 channels are selected for a 4 second delay after 1 second the 32 channels at t 0 are in the first portion of the delay device 12 after 2 seconds the 32 channels at t 0 are in the second portion of the delay device and the 32 channels at t 1 are.
