A pulse input apparatus comprises an input circuit for sampling each of input signals for a plurality of channels, an orthogonal memory for storing the sampled signal components of the input signals, sequentially in a direction of its time axis, and a sequencer for reading the sampled data items from the orthogonal memory, in a direction orthogonal to the time axis, to obtain a code representing the time at which the input signal has changed, in accordance with the command read out of a command memory. The sequencer measures the time of the change from the code and the present time, and then adds the measured time to the corresponding command, and stores the time into the command memory.
