ABSTRACT:
A printing apparatus for multiple signal printout has separate multiplexers for analog and pulse channels. The multiplexed analog signal is digitized, formatted, and applied via a selector to an adder, alternatively and selectively, the pulses are applied as digital signals to the adder. The adder receives zero offset numbers which differ for the different channels and the resultant numbers are applied to a one-out-of-n decoder driving printing electrodes. The system is under control of a cyclically addressed ROM whose outputs controls the multiplexing and furnishes the offset numbers. A clock sequencer times each acquisition frame.
