First Claim
Patent Images
1. A high-speed acquisition system, comprising:
- analog signal input means and analog output means;
an analog bus coupled to said input means and said ouptput means;
a plurality of analog memory means disposed in M rows and N columns, said analog memory means being coupled to said analog bus; and
means for activating said analog memory means in a predetermined manner to provide store and readout operations, said means for activating said analog memory means comprising an X shift register having M outputs and a Y shift register having N outputs, M row control lines connected to the outputs of said X register, N column control lines connected to the outputs of said Y register, and means for operating said X shift register at at least one predetermined rate and for operating said Y shift register at a rate 1/M times the rate at which said X register is operated, wherein said row and column control lines form an M×
N matrix of electrical intersections each of which corresponds to an analog memory means, each of said analog memory means being connected to both a predetermined row control line and a predetermined column control line for activation thereby.

Abstract
A high-speed acquisition system employing an analog memory matrix is provided in which sample-hold elements connected to an analog bus are arranged in rows and columns to form an M×N matrix. The system is operable in a fast in-slow out mode, and the analog memory matrix may be implemented on a single integrated-circuit semiconductor chip.
