A train of rectangular voltage pulses that alternate between two fixed values for equal lengths of time. The time of transition between each fixed value is negligible compared to the duration of the fixed value.
Square wave.
A pulse train in which all the pulses are of equal width, the mark-space ratio is unity, and the frequency is constant. The diagram shows how such a signal, when displayed on an oscilloscope, may appear.
Square wave.
A pulse train that consists of rectangular pulses the mark-space ratio of which is unity (see diagram).
