Radio Controlled Clocks
a peek under the bonnet
Recent advancements in circuit integration have drastically reduced the production costs of radio-controlled clocks. These days they are not much more expensive than their conventional quartz counterparts. This article gives us an insight into the design of an analogue radio controlled clock.Convenience and reliability are probably the biggest attractions of a radio controlled clock. Standard quartz clocks are accurate enough for most purposes but with a radio controlled clock there is no longer the need to periodically synchronise it, compensate its movement or add or subtract an hour. All it needs is a fresh battery every so often and it will carry on showing the precise time and date through leap years, leap seconds, BST and GMT.
