Archives:Digital Signal Processing Comes of Age: The 1970s



Some historians have seen in the 1970s the beginning of the Third Industrial Revolution. The First Industrial Revolution, characterized by steam power and factory production, began in the late 18th century. The Second Industrial Revolution, characterized by electric power, the intemal combustion engine, and telegraph and telephone communications, began in the late 19th century.
