Apparatus for converting a train of code signals representative of a letter, number, or symbol to a visual display of such corresponding letter, number, or symbol. The train of signals includes individual signals of at least two distinct time durations, the length of the time durations being dependent upon the proficiency of the operator initiating the signals. In the signal converting apparatus, a clock signal of a preselected time duration is produced. The time relation of each of the signals in the train of signals is resolved in relation to the clock signal. A first signal is produced if the signal being resolved is less than the clock signal, and a second signal is produced if the signal being resolved is greater than the clock signal. An addressor receives the first and second signals and stores the signals to generate a given address dependent upon the particular first and second signals and the order those signals are received. The addressor produces a signal indicative of the given address. A memory contains a respective letter, number, or symbol corresponding to each address. The memory is associated with the addressor for receiving the signal of the given address and producing a signal representative of such respective letter, number, or symbol of the address. A sensor detects the end of the train of signals and produces a signal indicative of the end of the train of signals. A visual display is associated with the memory and the sensor such that the visual display receives signals indicative of the respective letter, number, or symbol of the given address and produces a visual display of the respective letter, number, or symbol when the end of the train of signals is sensed.
