Abstract
Abstract A single diode matrix is used both for decoding encoded information and encoding uncoded information. The column lines of the matrix are connected to receive coded signals, and are further connected on the same side to furnish coded output signals. The rows of the matrix are connected on one side to receive uncoded input signals and, on the same side to furnish uncoded output signals. The other end of the column line is connected to a zero voltage source which is set in response to any incoming uncoded signal. The other end of the row conductors is connected to a 22 volt operating voltage which is set in response to receipt of any coded input signal. The signal for furnishing the 0 and 22 volt operating levels are derived from a second and first OR gate respectively. The output of these OR gates are also connected to a third OR gate, whose output thus furnishes timing signals.
