1. A high speed data acquisition system for storing a succession of analog signal sample values comprising analog signal input means and analog signal output means, a first analog input bus connected to said analog signal input means and a second analog output bus connected to said analog signal output means, a storage array comprising a plurality of cells arranged in rows and columns, row clock means coupled to said storage array for selectively activating each row of said storage array, column clock means coupled to said storage array for selectively activating each column of said storage array, said analog signal input means being directly connected to said storage array for supplying an analog signal to the cells of the array, and means responsive to the row and column clock means for successively activating each of said cells for storing a succession of analog signal sample values comprising samples of said analog signal, each of said cells comprising a pair of gates connected between said analog signal input means and a first capacitor in said cell for causing said first capacitor to store each said analog signal sample value, said gates being responsive to said row and column clock activating means, each of said cells comprising a voltage follower coupled to said first capacitor, and a multiplex output device connected between said voltage follower and said second analog output bus for transferring a proportional represntation of each said stored analog signal sample value to said output bus.
