What is a square wave?

square wave is a type of progress where the signal has only two levels. Switching the signal between these levels at regular intervals and the switch is immediate. These properties mean that the wool graph creates over time with square corners. The square wave has practical uses in digital circuits and music. Such progress gradually switches between two levels, so the graph of the wave over time is a series of curves. The waves of the sea, waves and sea waves, all follow the sinus formula, as well as the level of voltage in the AC system. The best known of them, including square wool, triangle and saw waves, also include a signal that fluctuates between two levels. However, each of them behaves in a different way, characterized by whether the switch in both directions is insjakán or gradual, how long the switch and how long it will pass between the switches. The names come from the way the wool graph creates a suitable shape over time. Immediate changes of the square wave in both directions means thatE The graph is shaped as a castle turret.

The

square wave is relatively simple for artificially generating. This makes it particularly suitable to ensure that different parts of the circuit are correctly synchronized. The regular square wave pattern acts as a timing device. The square wave can also be used for synthesizing sounds in music. The sound wave that follows the square wave formula sounds similar to wind instruments such as corners, triggers and saxophones.

In fact, it is impossible to generate a perfect square wave. This is because the device used to generate it will be certain physical restrictions. For example, the connection used in the telelectric circuits of the device will have some resistance that delay the change in voltage levels.

The

square wave is sometimes also known as the Rademacher function. This name comes from Hans Adolph Rademacher, a German mathematician who emigrated to the United States. In addition to contributing his own work to mathematical studies, he taught a number of students who also became leading academics and researchers in the field.
