As digital alarm have become more sophisticated the power consumption used to power these devices has decreased and most digital alarms are powered by batteries now. Some larger led digital alarms are still powered by main electricity.

Modern digital alarms timing mechanisms are run by quartz mechanism’s which makes them extremely accurate, digital alarm typically use the 50 or 60 hertz oscillation of AC power or a 32,768 hertz crystal oscillator as in a quartz clock to keep time. There are also models that have been designed which are radio controlled as well, this means that their time is set automatically by a radio signal which synchronises the time of the clock with the national radio signal.

Digital alarms have come along way since the first version appeared all those years ago and many manufacturers today make a wide range of digital alarms, with some of the sort after features including lcd display, ipod docking, dab radio and projection devices.
